I like achievements, and as long as they implement them in a way that you actually unlock something with them, or unluck them by getting some sort of extra, like artwork, more costumes or you name it, they could work on any system.
Someone mentioned lords of shadow, the achievements on that game were good, because in order to get them you just had to find everything in the game, and that required exploring the game, purchasing the beautiful artwork ( this is one of the reasons i love the game), completing trials on each stage.... those seem like good challenges for all players, and that´s what i did in, for example,on every zelda game i´ve played so far, and if they could come up with a way to get something more out of unlocking them, like avatar stuff or whatever, the better, and not just be some "do this ridiculous thing for no reason" type thing.
I hope i made my point clear =).
