360 Achievement Points

[DreadPirateCash]

What do you guys think of the achievement system that Microsoft uses? Personally I think it's a great idea and I enjoy it thoroughly but I'm also the kind of person that uses my save games as a status symbol. I haven't played too many games on the 360 because I've only had it for a few months but one of the things I found that really bother me are the time based achievements. Like "Play for 50 hours" to unlock and such. I'm the kind of person that will play a game, annihilate it and move onto the next one and it really sucks when I've got 49/50 and the last thing I need to do is play for 10-15 more hours when I've got nothing left to do. I hear tale that PS3 is starting a similar system but I don't own a PS3 so I don't know if it's been implemented yet.
