The Goods on Crysis 

The ability to operate a variety of land, air, and sea vehicles such as helicopters, tanks, bots, and trucks is a huge feature for me. I am of the Battlefield franchise fanboi club so I love being able to control different vehicles and weapons.

32 player online multi player is also a pretty great feature.....it's not Battlefield's 64 player game but in all honesty those can get pretty maddening at times. 32 seems like a pretty middle of the road number to me and I think it will satisfy the competitive FPS community.

The CryENGINE 2 engine from Crytek is something that I have been watching since they announced it quite some time ago. This engine looks amazing and it could change FPS environments and physics forever. From what I have seen of thing it's very impressive. This game is absolutely beautiful.

Real time Armor and weapon customization doesn't look like a big deal to me but it could raise the required skill level as you have to react fast during battle to use power enhancements. Always a fan of fighting the button smashing in any way possible so although small this looks like a decent feature.
