It's staggering how many Japanese games there are that never make it to America. This is understandable in part: many of these games are poorly made, or are otherwise totally incomprehensible for American audiences (case in point, Sega's Sukeban Shachou Rena, about a cat who has to run a Japanese business. Wearing a cat suit). Then again, some of them just don't seem like they would find a very receptive audience with Western gamers (Sukeban is one of the worst selling Wii games to date, even inside Japan). Although only import gamers could say for sure, most of the time this seems like a fairly accurate assumption.
