Graphically this game has to be seen to be believed. The Patapons themselves are actually little more then black eyeballs with arms and legs (and large weapons). The variants you make with different materials are usually larger, different colors and hairy for some reason.
You should either be playing Patapon or running out to buy Patapon! This is one of, if not the best, games on the PSP and at a shockingly low price of 19.99 USD and CDN in the Great White North, buying this is a no brainer.
