Um I dont think gears of war 2 was a FPS...I played the first one and it was third person...so I believ part 2 was third also....

In no particular order (you can't make me choose)

Goldeneye 64
Perfect Dark 64
CS 1.6
TimeSplitters 2
Star Wars: Jedi Knight

Half Life
Quake 2
UT
UT2004
Half Life 2

In order those are my top PURE FPS, no Deus Ex no Thief etc.

^ I TOTALLY FORGOT TO ADD UNREAL TOURNAMENT... DAMN IT!
so now i add it, thanks or reminding me Vlad

1. Half Life 2
2. Goldeneye 007
3. Doom
4. Perfect Dark 64
5. Halo

Out of the ones I've played of course. Metroid Prime and Bioshock would be somewhere below that. Bioshock so far would be the only one this gen worth adding. Maybe COD4 but I still haven't done the single player yet cause always playing online. Oh well.

1. Enemy Territory: Quake Wars
2. Return to Castle Wolfenstein
3. Star Wars Jedi Knight
4. Far Cry 2.
5. STALKER

1) Halo Series
2) Goldeneye 007
