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.

“Originally envisioned as an expansion for Valhalla, the game was reworked into a standalone title to expand its scope.”
It really disappeared from the public consciousness 😀
