Good article on the localization history of the Yakuza series.
http://www.1up.com/do/feature?cId=3178466It certainly would be difficult and unnecessary to localize something like Shogi or Answer X Answer, but I'm still a bit skeptical at the reasons for axing the Hostess Bars. Then again, I barley bothered with them in Yakuza 2 and it sounds like I wouldn't bother with Shogi or a trivia game either so, other than some side quests, I don't really miss all the cut content.
