I think it looks really cool. I've been wanting a game like this ever since RDR2 showed that this concept could be really interesting.
I guess I can kind of see how the game could be offensive in a "you're monetizing and making a game out of my people's and culture's genocide" kind of way, but by that logic, every single WWII game ever should be banned, too, and we all know that's not gonna happen.
Look, I'm not gonna pretend that the Natives weren't given one of the rawest deals in history, or that they were all peace-loving hippies, but what's done is done, and one game is not going to change that.
It sucks, and my heart truly does go out to all millions of Natives that were killed and displaced, and I really do wish things had happened differently, but we can't make things go back to the way they were without literally plunging the entire world into chaos. Somethings just can't be fixed.
If anything, maybe the devs could give some of the profits to a reservation, or something, but I don't think they should be forced to. They should be allowed to make their game however they want, and do whatever they want with the proceeds.
Besides, if actually does turn out to suck, then we can at least still make fun of it, and joke about how Eagle Flies and Pocahontas didn't die for this, and shit.
