F.E.A.R. is not oly the freakiest game I've ever played, but also has the best gameplay and graphics.
The graphics are the best I have seen (playing on a 7800 GTX). The particle effects are incredible, the sparks fly and add breathtaking realism. The gore is intense and fun to see. The textures are highly detailed and the bump mapping looks great. The soft shadows are not done very well, but as most games dont even have these this does not take much away from the game.
The gameplay is superb. I have never enjoyed any single player moment more than when I went into slow-mo and blasted a guy away with the shotgun. It is the most fun element ever put in a game and 50% of the reason I bought F.E.A.R. It looks so realistic and watching the beautiful physics in slow-mo is not a soon forgetable experience. The only qualm I have with the gameplay is the ghouls at the end of the game, not realistoc at all, I like fighting humans, not fake spirits but whatever.
The sound is fine, not something I pay much attention to but it really creeps you out.
Value is not a strong point, although the game has a ton of replay value due to the fun factor it is not a very long game, taking me 7 hours max to beat on moderate difficulty. The MP is not especially trilling either though it is fun to play MP just to look at the gfx.
Overall the game is certainly worth the money for the intense experience and I give it a 93%.
