Lots have already been posted here, but here's a good list:
Bully: lots of different and fun acievements, with only one annoying one (100% the game);
A.Creed: play through the story and do all the mini missions. Ignore the flag ones unless you have a guide.
Bioshock: most gotten by playing the game, though have a save point before the end of each level so you can go back and get some that would normally need 2 play throughs. Also, research everything with the camera.
Fallout 3: same as Bully w/o the 100%: you just need to play A LOT. Save before hitting each good/evil achievement level, and then just abuse karma to get them all.
Lego games: mentioned above.

Can someone tell me some for PC on windows XP? I've got quite a few on Gears but I'm struggling to find more games with achievements for windows XP.
Halo 2, Fallout 3. Dunno any others.
