It depends on the game and whether I enjoy playing it,
Call of Duty 4: 1000 of 1000
COD MW2: 880 of 1000
Forza 2: 970 of 1000
Forza 3: 660 of 1000
COD WAW: 1445 of 1500
COD 2: 1000 of 1000
I only have 6 with over 1000, but I'm pretty close on others, and then you have the impossible achievements, like the one I'm missing for Forza 2 :
1,000,000 Online Credits
Earn 1,000,000 "Online Credits" from Tournaments and Career races.
Come on, seriously?
Anyone else run into any glitched achievements and gotten screwed? I think an update screwed me on UFC Undisputed: Roster Run-through
Complete one fight in Exhibition Mode with each UFC fighter.
Kinda pisses me off to work on something and then get screwed out of it.
