While surfing the internet I've read comments by several people to the effect that Killzone 3 was terrible in compairson to Killzone 2. I seem to remember most complained about the story.
I personally liked Killzone 3 more than Killzone 2. One particular change I liked was that in KZ2 while you were in cover in order to aim down the iron sights you had to first lean forward with the left stick and then press R3 to aim. However in KZ3 all you have to do is press R3 and you lean forward automatically. Its a small thing but it makes a huge difference in how you use cover.
Another good change the addition a heavy weapon slot and the addition of ammo crates. Much easier to go through a particular level and use the weapon you want.
The ISA part of the story wasn't as realistic this time but still good in popcorn movie sort of way. Also I loved the bits focusing on the Helgast.
What do you guys think? Did you like Killzone 2 or Killzone 3 better and why?
