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.
Odyssey and Valhalla were both more on the RPG side, Mirage went somewhat back to form, though not fully. Could be they split between the two types, but based on Valhalla and Odyssey it’s more likely to me that Yasuke and Naoe’s gameplay loops aren’t super different, maybe some techniques (e.g. he throws a knife that does x damage, she throws a kunai that does x-5 damage + poison, or something like that.) and a couple story elements relevant to them.
