I didn't realize until the Penny Arcade post that the avatars in LittleBigPlanet are called "SackPeople." That really sounds like it ought to be an insult or something. Like, "Hey Sephiroth! You're a sack person!" Though i guess that's not really something Sephiroth needs to worry about because other than Cloud no one is going to risk taunting him like that. Anyways, i generally like chibi, but the sack person aesthetic does not seem particularly appealing to me. In fact they look a little creepy, at least to judge by these examples.
