my favourite games of all time, not really in any order:
Half Life and Half Life 2 (definitely my favourites, has to be at the top!
Battlefield 2
CoD1, CoD United Offensive
CS Source and Day Of Defeat Source
Farcry 1
Warcraft III
GTA SA
Deadly Dozen (quite an old game, vietnam war i believe)
Max Payne 1 & 2

Haven't got F.E.A.R yet, but am sure its gonna be right up there next to Half Life!

metal gear solid all the way

GTA SAN ANDREAS - Best ever fellas
Peace

the Fallout series does it for me, but Fallout 2 is definately my favourite game

Other ones i like:
F.E.A.R. (got it a few weeks ago, multi-player is complete chaos in a full 16 person server, i love it!)
Alot of the old NES games i have
Halo and Halo 2 (XBOX)
Fable (but it was too short!)

Games i'm looking forward to:
Elder Scrolls VI - Oblivion
S.T.A.L.K.E.R.
Stubbs the Zombie in Rebel without a Pulse (something about beating people to death with their own limbs is just so damn appealing!)
