The Pandyssian Continent is largely uninhabited, save for a few trading posts and explorer camps.
Yeah, according to people from the islands who literally just started tiny bits of exploration like fifty years ago, and who don't actually know anything about the continent aside from a whole host of rumors that have existed since before they even left their little bubble in the corner of the world.
I doubt that there would be a civilization there, and an eastern ninja type game would not be Dishonored, it would be a steriotypical ninja game
That's stupid. Dishonored was literally created with the idea of being a "ninja game," eastern-style setting included. There is nothing more "Dishonored" than ninjas. Just because we happen to have a story about a western one doesn't mean that he's not a ninja, and uh, honestly? When was the last time you played a game that was actually about being a ninja? Ninja Gaiden doesn't count, so Tenchu? Only those games haven't been good since the last real one in 2003, and were also third-person just like every ninja game ever.
Dishonored is a unique world, and there would not be eastern style ninjas in it.
First of all, it's pretty presumptuous of you to say something like that considering you know just as much as I do about the setting. Being a "unique world" has done nothing to prevent the setting we will find ourselves in from being a carbon copy of industrial revolution-era England. The history and lore is unique. Nothing we've seen of the "world" so far looks unique at all. There's literally no reason to believe that there couldn't be eastern-style civilizations in the world, unless you think that this tiny section of islands is the only settlement on the whole planet.
Also, honestly, I wouldn't like a game like that.
Opinions, etc. But really you're saying that even with awesome gameplay you would skip out on it just because you don't like the setting? I just can't imagine hating any setting that much. Did a ninja kill your family?
