There is no limit to what game it may be. Doesn't have to be as lengthy as mine, I just have a thing for this one. I'll get it started.
Resonance of Fate / End of Eternity(JP).
This game has Comedy, Action, Drama, Romance, Tragedy, and some Dark moments.
It was a 9.2/10 for me. Just a personal favorite game that has taken a special place in my heart.
I've been a pretty big fan of tri-Ace and all its works since Valkyrie Profile on the original PSX, so when I saw this and the Seiyuu list it got me pretty hype.
Spoiler:
Hiro Shimono - Almaz von Almandine Adamant(Disgaea 3), Ash(Phantom Brave), Katsuragi Keima (The World only God Knows.
Aya Endo - Takara Miyuki(Lucky Star), Kirigaya Midori(SAO), Tesso Tsuduri(A Certain Scientific Railgun [s])
Nobuyuki Hiyama - So many things...
Keiji Fujiwara - Equally as many things....
There's alot more but those instantly stuck out to me.
Complete with JP audio, this game had its hooks in me from the start.
What made this game so incredibly difficult was it's technical system. While battle system looks simple and straight forward once you explore it's depths it'll make suicide look like the glamorous option, for taking the time to learn it.
The game has a 'tutorial' system in the neighboring arena where you can learn the sheer basics of combat. There are probably 23 options when they ask "would you like to learn how to fight", and in the 20+ options, there are 4 or more pages explaining about that particular topic. While 15-16 topics focus on combat, the remaining discuss options a bit(Scratch damage, direct damage, Action/Hero Gauge, Attack Gauge, Heroic Action, weapon attachments, weapon attributes, leveling up..).
What they never cover in game and you simply discover on your own is, dismantling, the Hero Gauge and Tri-attack 3 extremely important elements in the game.
Dismantling can obtain an absurd amount of fabrication items which is used to create certain weapon parts, grenades, and things that take the load off battle and make it slightly easier.
They tell you what the hero gauge is, how it's used, and how to obtain more, but not this stuff. The Hero Gauge is used to inflict A LOT more damage and allows for strategic movement and enables Tri-Attack when certain conditions are met. Poor use of the Hero Gauge will inevitably kill you, and fleeing battle when your Hero Gauge is not full will make you wish you didn't use it.
Tri-Attack is what makes or breaks boss fights, setting it up is hell-in-a-hand-basket, but incredibly rewarding. If you execute it correctly you can easily knock out 30-90% of boss HP depending on the circumstances(Bonus Shot, Hawk Shot, Beat Downs etc etc) but if you botch it, you may as well hit the retry battle and pay the fee to start over(Yes, you pay a small fee every time you lose a fight, you restart battle with the same conditions you came in with.)
Once you actually start playing the game starts off nice and easy, simple enemies, with low health and armor, relatively the same level. Once you get past a certain point, the game becomes incredibly unforgiving and extremely difficult. Enemies have obese amounts of health, and incredibly difficult position on their article of armors. There are points where you fight as many as 10-12 people as once with 2 party members. Consider 5-6 with 3 members already fucking difficult.
There is two save points in this game, 1 at the main base, and the second is a resting point you can set up at the traveling menu when certain requirements are met.
There are sequenced encounters in the field where you can obtain Bezel shards(Collect 4, +1 Hero Gauge), where they are extremely difficult and you cannot flee from them once you engage.
Normally in most games leveling up is a good thing. In this game leveling up is an absolute mandatory thing. Because in this game there are three-ways to level up. By pistol usage, SMG usage, and Grenade usage. Think of it this way.
Zephyr with level 20 Pistol, SMG, and Grenades, is better than level 60 Zephyr with Pistol alone.
There are alot of things that make this game difficult but the fact it's so technical makes it a WHOLE LOT more harder, but in the end I still love it to death.
There isn't any hand-holding, simply learn and adapt. The way games are meant to be played. It took me about 100+ hours to beat it because I had to grind and grind but it was worth every moment.
The only game I remember playing and being extremely hard is "Yggdra Union: We Will Never Fight Alone" for GameBoy Advance.
It is a Turn-Based Strategy game that uses cards to allow your units move and attack. Units health is "Morale" and once it reaches 0 the unit dies. Some maps are about protection, cover, reaching a location and almost all maps have secrets, like hidden events, items, scenes, etc. You can make formations depending on the gender of the unit, female are "+" formation and male are "x" formation and you can assemble subformations too ("+" + "+" / "+" + "x" and so). There are Items and they have a strange role, if you "use" the item, it will restore morale, but depending on who you use it, it will restore a lot or a few points. You can also equip items to units and will grant them special stats. Although the game has a tutorial, it is extremely difficult to get a grip of the game after playing it, at least, I needed to look for info over the internet and play the same 4 or 5 first scenarios several times before I started to realize how to play the game "correctly".
Cards have a weapon, skill, element, power and moves. The weapon can make a card weaker or stronger against the enemy card in that turn and depending on which unit is attacking/defending (i.e. your unit uses axes and you used a card with axe as weapon, you will inflict more damage). During combat you can charge a bar to unleash your card's skill. The element is similar to the weapon thing and depends on where on the map you are standing/fighting (i.e. water, terrain, mountain, fort, village). Power determinates how much moral your/enemy unit will lose after a combat. If your card has high power and you win, you will probably (late game units have tons of morale and need more than 1 attack) put its morale at 0 and kill the unit, if you lose, you will signifcantly decrease the moral reduction of your unit. Finally, moves determine how many steps any of your units can move and all the steps are shared so if you can moe 6 steps and have 3 units, those units share the 6 steps and you have to distribute them. All of this applyes equally to the enemy.
To kill an enemy unit (or lose one of yours) it is neccesary to reduce that unit's morale to 0. To achieve it you have to use cards with a very high power or attack that unit with more than unit (i.e. formation). Also, after each combat (doesnt matter if an unit died or no) the Card used in the combat will gain have its power increased based on the performanced done by the unit/s.
About formations is quite the problem because if you are careless with your cards and moves, you can end up facing 1 unit against 3 or 4 enemy units and lose that unit. You should always try to match units with element, weapon, terrain and enemy and ally units so they can take advantage of the formation system. When yo do the first formation the "+" or "x" extends 3 square from the center of your unit, the units chained will extend the formation "+" or "x" just 1 square from their center. I want to note that formations can be sometimes absurd since you thought you were doing a 3v3 and actually you were engaging 4v5 or viceversa.
Items and Cards are honestly a pain in the ass because you have to be extremelly careful if you dont want to waste both of them and their moves/utility/morale restore capabilities. Some items are edibles (1 use) and will permanentl increase one or more stats of your units, whereas others will just (normally) increase it temporary. Some items grant temporary skills and/or inmmunities, same go with cards' skills.
Stats and Morale depend on the uni, some units have much more morale (say like tanks) than others and some units do more damage than others. Stats are GEN, ATK, TEC, LUK and REP. GEN is the defensive stat, how much morale the unit will retain after loosing and the units ability to defend against cards' skills. ATK is the damage done by the unit during combat and the power of the morale destroyed of the enemy unit. TEC is about making your units landing your cards' skills to the enemy, so GEN and TEC and compete against each other. LUK is about critical strikes when charging (before combat starts), defend against an enemy charge and to prevent or deliver flash attacks during combat. REP is a very weird stat because it is rarely used and it is only "useful" to obtain items when you step in the right place/village of the map. If a unit wins a combat, it will gain REP until a maximun of 6. Whenever that unit lose a combat, it will lose all the REP it had. Depending on the type of unit (i.e. Cavalier, Mage, Melee) it is recommended to focus on one stats, say Cavalier GEN (to absorb damage and prevent charges and skills), Mage on TEC to do skills and Melee on ATK to do as much damage as possible. LUK is "useful" to obtain certain items during the game (which are quite needed tbh, though they are hard to obtain). Normally, Melees have high ATK and LUK for that purpose.
More or less, that is all. To be honest, this game has 2 version, "Original" and "NA Version". The first one is the one from Japan and its difficulty level is settled on the maximun level by default and is impossible to change it. The second one is the one that was made for NA and allow players to adjust difficulty so the game IS ACTUALLY defeatable. I got so frustrated the first couple of times I played the game that I dropped it and after some time, try it again, it is extremely hard (for me at least).
F-Zero GX is the toughest and best game I've played.
Everything is against you in that game. AI racers are aggressive, smarter and faster than you, tracks are brutal with corners that require good reflexes to pull off without losing major speed, which is a race-killer in this game easily putting you from 2nd all the way back to 26th. And that's only Grand Prix.
Story Mode is another beast from hell altogether. If you thought the GP was bad, just wait till you tackle this baby. They somehow found a way to make the game ever harder. You have so little or no room for error, a simple crash or grazing a wall is enough to screw up a 3 min run. It's pretty much trial and error until you get it, and nothing less than perfection will ever be enough. Luck doesn't even factor here. It also doens't help that you're forced to use Captain Falcon and his shitty Blue Falcon. It takes like 2 fucking minutes for that thing to reach top speed. And no, you can't skip the mode because that's the only way to unlock all the AX racers. Good stuff.
It may not look like it, but beating that mission is one of the toughest achievements in all of gaming. I did, and I consider it the greatest moment in my life (yeah, I know >.>)
Funny thing that I recently got Resonance of Fate myself awhile back myself but haven't got into it yet since I'm still learning the battle system.
My current list of hardest games to date:
Bayonetta: Great hack and slash that follows in the footsteps of the classic Devil May Cry series, just playing on Normal in various levels will get your ass handed. One of the few games I learnt the hard way that dodging is essential to surviving in tough spots.
Metal Gear Rising: About the same level of Bayonetta in terms of gameplay, even harder if you're trying to complete the VR missions with a top score and beat the bosses without getting hit on the highest difficulty for its trophies.
Medal of Honor: Frontline: Hard mode. Enough said on this one.
Chaos Legion - Some boss battle (and in some chance also battle with normal enemies) are pretty hard, unless you go back to replay previous levels(that can be done after passing a certain level) to get soul/exp to enhancing the character, which require a lot of it.
And theres more
Samurai Warriors - Not enough time to fulfill some of the mission in the story mode,
also playing at chaos difficult is almost impossible
DMC3 was the last real challenge for me in the series. DMC4 was just eye candy on a new system. Fights were watered down but it was still hella entertaining.
God Hand, dear mother of god. It's bad enough the game on normal is hard as balls. It only gets harder if you continue to do well during the game. I managed to beat it on hard mode and that was still profoundly hard because of the built in enemy level up system.
I actually managed to beat QWOP by shuffling along the ground for however long. But then they fucking trick you and put a pit before the finish line. Thank god I managed to jump over it or I would have been so pissed.
Tossing in a vote for God Hand as well. First game I'd seen that actively punishes you for doing well lol.
DMC 3, I can handle (once you had enough practice and skill), God Hand on the other hand was fricking brutal. I never even got passed second to last boss (he was the old man who turned into a fly if I recalled). Like in Bayonetta, dodging is essential in God Hand for beating it.
(he was the old man who turned into a fly if I recalled)
... you had trouble with Belze? Really?
As embarrassed as I am to admit it, yeah. I never got a pattern to beating him because of his high defense, he takes forever for his life bar to drain with the right combos.
Getting the A+ and band-aids is damn difficult and you need them all to access the true ending. Still working on it, but I got the original ending at least.
But then again, those were designed for you to eventually commit suicide out of pure frustration. It still blows my mind that people speedrun those games...
Kaizo Mario is equally as difficult, but is actually pretty fun even though you will die a million and a half times on the first level (Even the opening screen that welcomes you to the game can, and probably will, kill you).
Offical release games: Battletoads
Beat it once (only once) and I'm never touching it again. Still haven't found a game as hard (broken) as that game (atrocity). Reason why its so hard? It's fucking Battletoads...
Toughest game I ever beat has to be Demon's Souls. It's only slightly harder than Dark Souls, but partly for reasons that they fixed in Dark Souls. It should be fairly obvious why I say this is the hardest game I beat if you've played it before.
The hardest game I've ever played would probably be Ikaruga. It makes bullet hell games even harder because not only do you have to dodge bullets but you have to make sure you're the right color so you don't get destroyed by the ones you're trying to absorb. It gets fairly disorienting and I haven't beaten the game yet. It's fun as hell, but also very hard.
