I also enjoyed the hell out of F.E.A.R., though I only have the 360 version (which I know is far inferior to the PC version). Good luck finding players for any version, though. Last time I hopped on Live I think I found like 4 people to play with after almost a half hour of attempts.
Anyway, the only gripes I really had with the game were the severe lack of character development on the hero side (Point Man = faceless, speechless protagonist) and the level design. More office buildings than you can shake a stick at. Even though it was repetitive, I still got a good couple of scares which is what I came for in the first place.
