keep all the extra stuff on the PS3 but make it a bit more expensive than the lacklustre 360 version (or do the opposite, make the 360 version a bit more cheaper than it's "normal" price).

It's annoying 360 is lacking in space, but it kind of makes it seem more like the old VII to IX game play, which is in no way a bad thing.

PS3 has gone down in price recently with the new slim line.. and it is awfully tempting..
