Damn it seems kind of weird that people are upset over this one thing in particular, but on the other hand I can't think of any good examples of video games that were not historically accurate and no one got upset so it's probably pretty normal and also I think the fact that the year of high school I missed was the one where history class is devoted to samurai means I don't have a good handle on how much this inaccuracy destroys the immersion for a normal person.
