1. replays after each kill are a pain. It should be deactivable and replaced by a std countdown before respawn. It will give little pause to the player between each kill. Rather than seeing again his own death and get more & more on nerves.

2. without any MP game mod that can last last 30mn , 1h, or more (like Crysys wars power battle), the MP game will quickly become annoying. Once people will think they have collected enough upgraders.
with 5mn limited parties, (for some players), you have even no time to get into the game!
less options, less players
this point 2 is probably the biggest issue
3. no tanks, no planes, nothing ; small maps .. ! ok Crytek will sell an extension module with new game mods . marketing.

4. launching grenade takes too much time. Switching weapons too. And again, we can carry only a few.
5. can't lay on ground to adjust --> can't say it is realistic no ? and what is both unrealistic and limiting capabilities is.. frustrating !
6. the weel in Crysis 1 with strenght / speed / armor mode was so good ! very fast, very usable ! unmatched by this version of nanosuit
7. because A/E are used for suit modes, cant find a decent place for strenght punch (no, V is not well placed!)
8. needing to hold right mouse button to keep scope mode engaged is a pain
9. graphics are uncredibly good. buildings, lights,.. wow !
10. too much issues to find a server. too much lags in game also.
Make this game more playable, more fast (I mean for player to do actions; fps are good)
Score:
Crysis Wars : 9
Crysis 2 : 1
the only point where C2 is better are the graphics.
Crysis 1 was almost perfect (perfect balance between playable and realistic); but Crysys 2 needed to do things differently. So it ended to be just average. I hope developers can still change it / add options to it - to make it GOOD.

edit after another few days of playing
- MP parties are too short. A shame
- Replay of killings... is also killing the game
When you play x hours, it seems like you played only x 10 minutes, with a lot of boring in the middle
- And for whatever reason, you die really, really faster than in Crysis Warhead (And I know this, played 900hours+)
Crytek please do something!!!
