Playing 創世奇èšã‚¢ã‚¨ãƒªã‚¢ãƒ«. Yes, the 9GB monster, if you can't read Japanese.
First, it seems to a little alike to the Muv Luv series (or at least a similar setting) where humanity is attacked by unknown aliens. The setting is also much more horrible than before: Only 100,000 people (or was it was 10,000?) are left and alive on the Ark, and the entire world is covered in water as a result of the North and South Pole's icebergs completely melted.
This time humanity does not have humanoid battle mechs though. Jets, warships, submarines, you know the conventional. With combat resources running out (surprisingly, electricity is apparently infinite and solar powered and food is actually not too much of a concern) that the pilots had to conserve ammo on the battlefield, it seems like humanity is finally going to die, until an unknown power showed up.
Thus ends a short summary. Now for the complains.
First, does not measure up to JOKER-æ»ç·šã®æžœã¦ã®é“化師-, a work just out from the same company. Not too much of a complain though, they're obviously done by two different writers. JOKER-æ»ç·šã®æžœã¦ã®é“化師- has a much darker, realistic writing style whereas 創世奇èšã‚¢ã‚¨ãƒªã‚¢ãƒ« is all about HUMANITY SAIKOU! kind of optimism. Extremely obvious when there was a chapter dedicated to the 'evilness' of using nuclear warheads against a (I suppose it's not too much of a spoiler, but just in case):
at least 10 km long super fucking huge alien, whatever the hell it is. The shit could probably swallow the Ark whole with one gulp and these people are singing humanity's nobility. Unbelievable.
Fact is some hundreds of nuclear bombs are exploded everyday in reality as experiments, both small and big, and the VN is making a HUGE deal about exploding ONE nuclear bomb against a ALL HUMAN DIES level of crisis. Also apparently the writer did not do his research and thinks the last nuclear bomb used was in World War II - open warfare I concede, but the comment came out from a military officer. I find that incredible. >_>.
Well, still reading, and this VN is obviously not Muv Luv kind of despair style so, continue on...
