This year has probably been a record for me - until this year I never was a proper gamer... Just stuck with Halo PC and Oblivion mabey a few others but since I got into the achievements side, its helped me play through games several times and realize what I am missing if im not aiming for anything so in no particular order this year...
Halo 3
Halo 2 (PC)
Gears of War (PC)
Crackdown
Half Life 2 & Ep 1 (havent finished 2 yet)
Portal
Splintercell: Double Agent
Call of Duty 3 (I think)
Graw 2
Bioshock (Best game of alltime)
Battlefield 2: Modern Combat
Might be a couple more but wow!
