A lot of positive reception!
OK, so I'll most likely be going with Jade Regent.
The characters will be Minkai-descended characters, trying to hang on to their Minkai culture with Minkai mannerisms and classes (samurai, miko-themed divine caster, that sort of thing)
(For people who don't get it, replace "Minkai" with "Japanese" to understand what's going on.)
A human character, and only a human, can possibly be the heir to the throne.
Since there's so much interest, I might also do another game.
Based on Touhou, no original characters allowed - remake the canon characters with high-level Pathfinder characters. Like, Reimu is a cleric, Marisa is a wizard, that sort of thing. There're a gazillion canon characters to work with, so no shortage there.
And go through the plot of some of the Touhou games in a world where the formalized elegance and non-lethality of danmaku is replaced with merciless d20 combat.
Feel free to fangasm with me or tell me what a bad idea this is.
