Good graphics - average game
What disturbed me about the game was that it is simply too dark - the same problem which occured in Doom 3. Therefore the game tries to include horror elements but somehow it does not fully succeed (unless you play in the dark at night and you are dead tired). I think the main problem is that when everyone says even before the game has come out that it will be an instant classic like Half Life, everybody expects the perfect game. And if you bought a brand new Computer (which many people must in order to play the game) just in order to play F.E.A.R. then many people will be disappointed.
The main problem is that the graphics are impressive but just too dark. Why couldn't they do a level outside like in the outro ?
And once you played through the game (it'll take you between 10-15 hours) you will know the whole story and the suspense is gone. In my case there are a few missions which I still play from time to time, but that's about it. Therefore it is more a game which you should play through once and lay aside for a while to play again later.
The multi-player in my view is too dark and lacks the fun which you encouter in other games (hl2, cs, battlefield 2, etc) although I only tried it briefly.
All in all I would say that if you want to buy a new computer just for this game, hold on a little as it is not worth it yet. It is a good game but not good enough to be remembered as a classic.
For those who are horror afficionados and love to play in the dark (Doom 3 fans) I would recommend this game.
