Nice
It was interesting unlocking things, but I'm getting tired of achievments just for playing a game for X amount of time; makes the game seem desperate. "We never thought you'd play this for more than 10 seconds, so here's some points for doing absolutely nothing except letting the game run on your machine for a couple minutes!" Ugh.
Other than that, the outfits were good .. a HELL of a lot better than some of the other dress ups that have been coming out lately. Modern pop girl fashion is so granny and ugly. Goth/Emo girl fashion is still cool looking. Unlocking outfit combos was a nice touch.
