So there are a multitude of (I'm sure accidental) instances of US, EU and JPN versions of titles being split into seperate entries by mistake, and I thought it would be helpful for ioi and/or mods if we started up a long-running list of these - copy the list, and add any that you know exist.
I'll get the ball rolling. The following games have split entries:
Bleach Wii
Fire Emblem X
