I’ve found that the more similar pre-order bonuses between retailers are, the harder it is to choose which one you want. Take Dissidia Duodecim for example. The bonus is a costume wherever you order it, but which costume do you want?
Gamestop has the Cloud costume from Kingdom Hearts. You know, the one with the cape and the bandaged sword. Amazon has an alternate costume for Tifa, which is supposedly based on art by Yoshitaka Amano, the famous Final Fantasy series artist. Hit the source for pics. Dissidia 012 Duodecim Final Fantasy comes out on March 22nd for the PSP.
