Same, big massive black dude running around ancient Ireland killing all us wee pasty white ginger fuckers would definitely garner a stern look and a hard pass from me.. I mean, i get the whole introduce us to the world through the eyes of a foreigner angle... but fuck me, we've had japanese culture around for ages, we've all seen Shogun, we know they were badass and somewhat fucking bonkers so we didn't need any more introduction to their way of life, just give us a cool local protagonist and let us loose on Ancient Japan, how fucking hard was that to do!? You could've made the black dude a DLC ffs..
Anyways when they get around to setting an Assassins creed game in Africa, it'll be interesting to see who'll we'll play as...
