I don't think they cut that much, if any, from the game it fit it onto 3 discs. 3 discs is a lot already.
3 disc is a lot but most of it was used up by the textures right? Plus they had to compress more of it than they wanted to as well.
At any rate I dunno how people can not like the shooting in this game, if you are a FPS fan how could you not like the gunplay here--it has everything! From duck and cover, sniping, to all out balls to wall circle strafing blowing up faces! The game is incredible, I don't even see how some reviewers could have scored it so low...the Graphics, animation and Gameplay alone are the best i've played in any FPS ever! and that includes the first time I played Doom and Quake.
