Japanese gamers aren't impressed at all if you read the translated comments.
"Even though I didn't go on a trip to France, I experienced discrimination."
"Is this the rumored game where a black bandit who plays samurai in Nippon slaughters Nippon Jin?"
"When is the season for rice planting, cherry blossoms, and persimmons at the same time?"
"It's so scary to beat people to death in large numbers on the streets even though you say you won't tolerate bad behavior. Is he a samurai or something like a demon?"
"Yasuke was never a samurai, he was a servant that stayed in japan for less than 2 years, when his master nobunaga was killed, Yasuke begged to stay alive, later on, he left japan and went to india with the jesuit. Westerners are over glorifying him by calling him the legendary samurai.
And now in this game all the japanes bow down, while he goes around killing.
Why can't we have Musashi Miyamoto as samurai, Ubisoft?"
"Has a game about a black gangster with a Japanese male protagonist been released yet?
Please release it soon, UBI, I want to play."
"A torii is not the entrance to a village. Ubisoft knows less about Japanese culture than Koreans do."
"Thank you for the wonderful video that makes me realize once again how amazing Tsushima was.Thanks also to Sucker PunchWhat is a massacre with a family crest on one's back?Isn't this what bandits who were chased from their territory do, not samurai?"
To Japanese gamers Yasuke doesn't come across as a hero but as a brutish foreigner who breaks the Samurai code by hacking innocent Japanese people to death. Suckerpunch made the right choice in going for a Japanese protagonist who fought Mongol invaders. That's a much better starting point for a noble video game character who kills hundreds of people during the course of the game.
