"We also received a great deal of fan feedback regarding one of the missions in the original Crysis and discovered that it was really frustrating for players and that they felt it was just not that fun to play. That's obviously the last thing you want to be hearing as a game developer, so we made the decision to remove that particular level completely, and we believe that the game as a whole is actually better for it."
If it's the level I'm thinking of, it seems more likely that it was cut because the 360/PS3 would have a fit trying to render it. My mouth was agape the entire time you were in the zero grav section. Unless someone else can fill me in on what level they're talking about. I don't remember disliking any part of Crysis.
EDIT: Ok, the fights near the end of the zero grav sequence weren't great by any stretch, but to cut out a section of the game seems a bit much?
EDIT 2: So it looks like the level cut was the VTOL level, Ascension. I enjoyed that sequence, but I don't think it's a huge loss.
I'm still looking forward to picking this up, as I don't have a PC to play Crysis (played it on a friends rig).
