Hmmm, i've probably posted in here at some point but what the heck:
1) Counterstrike Source
2) UT (any game in the series)
3) Rainbow 6 3: Raven shield
4) Deux Ex
5) System Shock 2
Though system shock 2 is slipping down in my estimation, the first couple of times through were superb but after that the flaws in the game start to get really annoying.
There are many other greats, UFO enemy unknown, Civ 4, Fear, Baldurs gate series, Fallout Series, KOTOR series, The longest journey series... though I stick by my top 3 at least, between them they are all that is best about FPS which is my favourite genre.
