i don't know much about consoles as i am merely a mother. however, since i am a mother i guess my opinion is quite relevant here. psychoanuts is surely aimed at quite a wide audience, a lot of which are children. most families, at least in ireland, own ps2's, not xbox's.
the reason i got a ps2 as a family console was because it seemed more familiar, i guess, than the xbox. everybody knew what a playstation was. only gamers and my daughter knew what an xbox was.
although the irish do tend to be a little uneducated in things like this, perhaps it would be in scafers interest to release it on the ps2 as it seems to be more of a family console than the xbox.
