From what I've heard, From Dust's kind of a crappy console port with crippling Ubisoft DRM. I dunno if those issues have been fixed, but it kinda turned me off from buying it.
I bought it, I've heard a lot from what I'm assuming is the vocal minority but my friend said he had a lot of fun with it, and it seems like my type of game. Haven't had a chance to play it yet to try it for myself though, but it was so cheap I'm not that fussed if it's completely unplayable.
