Two different boxarts for PS3/Xbox360 versions. The Xbox360 one looks kinkier IMO, maybe because it's the Otaku box console over there. Interesting what rating this game will get in the West...15+ for Japan, so Europe might get away with a 16+ but an 18+ wouldn't surprise me. As for the US, M seems pretty much guaranteed.
Well, not a first for Atlus, Persona 3/4 are 12+ for Japan, but obviously the West finds them a lot more adult.

1 zillion copies will be sold confirmed

360 version looks much more boneriffic, if that what you mean by "prefer"

can i choose both?

I like both, but 360 just wins

PS3 version obviously!

I like the ps3 box

PS3 version.

just find the large version

don't know why but it make me feel 360 boxart better

I myself prefer the Xbox360 version... actually really wish reversible boxart would become the norm, because I'll be getting the PS3 version.
