I been playing Call of Duty: Modern Warfare (the original, not the sequel)

The game is very cinematic.. like watching a movie, but sometimes I feel I am not in control. Move there, shoot bad guy, game saved, move to the next place.

I can see why the game sold so much, but I am more interested about Crysis 2 "sandbox" approach, assuming it works; and non-quantum computers can run it.
