I'm sorry but I dont agree with the multiplatform ordeal here. Yes, it makes profit but you gotta think quality over quantity.
Crysis 3 should be made on PC only and should exploit the full capabilities of todays new hardware. I want to be able to be shooting back and have concrete debris spray by me when a bullet ricochets off the wall, jump from one building into the next one without hitting a load screen. Things of that nature. It is possible; however, the limitations are, like was said earlier, the 360/PS3 technology and the concept of multiplatform = more profit.
Multiplayer is fun, but gets repetitive after a while. I give Crysis 2 5-hours max until user gets bored either bored of it or finds out its just another FPS - toss back n forth grenades.
