Would I also get 360 achievements for playing it as well?

what has the pc to do with the x-box? besides that they have similar games from time to time? Nothing? Ähm No u wont , u need a X-Box xD

Well I heard some pc games give 360 achievements, in fact I've played one, age of empires online. However I'm wondering if it will work if you dl it as a torrent

yes you will, but only if its registered on games for windows live.

Thought it was something like that. Isn't fallout new vegas resgistered on windows live? I was hearing how people get achievements through pc, but curious about if it's torrented.

Steam has achivments also but they are not connected to your gamertag
also you need to buy the game new not torrent it
on christmas sale i got fallout new vegas and all dlcs for 8 bucks
you can wait for summer sale it will be probably for the same price(late june,early july)

yep, it needs to be registered with a cd key linked to your xbox live acc.

On steam? An if I link my xbox 360 to my steam account I can get achievements through that? If so I must just wait an do that.

naw, you cant link your 360 to your steam account, you can use your xbox live account for games for windows live though.
