Hmm, I shoud think oof getting one Realta Nua limited edition before they are sold out. Type Moon games are horribly expensive later if you want limited editions..
However the extra is a PSP game (I don't have a PSP) so I think Normal should be fine. Ahh, soundtrack limited edition, at least
Didn't know that Fate/ stay night is THAT popular in Japan, 140k copies in one week, wow..
