Yasuke is actually a fantastic choice as far as history/narrative goes.
A shame the game looks like more generic Assassin’s Creed Mapfucking+Crowd Supermurder.
Which is fine if that’s your thing, but I haven’t been thrilled by an AC game since… well, AC1.
That only works if your character is basically a blank slate story-wise, which just doesn’t work with all stories. That’s fine though, there’s plenty of games out there and not everything is for everyone.
