Best FPS game of the 2000s

[MrWayne]

That's hard to answer, the 2000s had so many great FPS.

Halo(2), CoD4, F.E.A.R, Team Fortress 2, Portal, Far Cry, Crysis, UT2004 were all fantastic games but I will choose Half Life 2.

Yeah HL2 is the safest pick but It was an incredible experience back then.
