Just for clarification, is the Wii version of Accent Core (US) the same as the PS2 (US) version (which I believe is the closest to perfection)? When I say "same", I'm referring to the absence of bugs and whatnot (that plagued at least the Japanese PS2 release). If not, would Accent Core Plus (Wii/US) fix those problems? I've already got Accent Core on PS2, but I recently got 2 sticks for my Wii, so I'd rather play on that.
