[quote name='Chlorox']Huh shoulda looked at the box art a tad bit closer. It reads "Games for Windows" not "Games for Windows Live." Which apparently means it does indeed not have achievements. Weak.[/QUOTE]
It not having GFWL is arguable. Games for Windows Live is a pretty horrible service. Sure it's nice to get the achievements, but the problems I've had with it don't really seem worth it.
The auto-patching is buggy as hell, it wouldn't even recognize DoW2 and didn't award any achievements (i had to delete my gamertag and recover it manually), I can't even play Fallout3 anymore because it won't connect to Live and when I try to reinstall, Live tells me the cd key I use is invalid or something.
Now I'm not saying that this is a rule, probably just the exception.
