resistance 2 is one of my most played games id recomend it to anyone

BioShock
CoD4
Modern Warfare 2
Killzone 2
Resistance: Fall of Man (NOT RESISTANCE 2)

And once you have those:

Unreal Tournament III
Battlefield: Bad Company
The Orange Box

And if you own ALL of those, and are DESPERATE for another:

Resistance 2

And if you feel like suffering for some reason:

Far Cry 2.

Warhawk is not first person but it plays the same so I would suggest Warhawk too.

Oh yeah and I forgot Borderlands.

Far Cry 2 is a lot of fun.

Killzone 2
Resistance: FoM
Resistance 2
Condemned 2

I approve of this list

Ugh. You enjoyed Far Cry 2?

Out Now:

- Resistance 1 and 2
- Killzone 2 (a must play)
- Call of Duty: World at War (not nearly as good as CoD4)
- Battlefield: Bad Company (pretty good)
- Rainbow Six Vegas 1 and 2 (Good games)
- Ghost Recon Advanced Warfighter 2 (Decent game)

Coming Soon:

- MAG
- Modern Warfare 2

Coming Eventually:

- Resistance 3
- Killzone 3

Much, much more than Killzone 2

For real ?
