If I play Fallout 3 via Steam, will I still be able to obtain Live achievements?

Since Steam usually has it's own achievements system and there is no mention of it on the page of the game, is it still possible to obtain Live achievements, or are they not availble in the steam version?

If you still can get them, how do you enable it to get them?

My best guess would be that you can still get Live achievements, that is, if you're logged in to GFWL (Games for Windows Live).

It depends what version of Fallout 3 you have (i.e. if it's the Game of the Year edition). Some people on Steam's forums are reporting that they haven't been asked to log in to GFWL.

You can get Live achievements from Fallout 3 when playing it via Steam (it's a Games For Windows Live game).

On the Xbox 360 the title of the game is "Fallout 3".
