First, I'm glad some people are reacting positively to the Artistic theme!
Second, when I first suggested the theme, I was thinking of "art" in a more expansive form. Not just visual forms, but also music, writing, dancing, etc. That way, Pokemon Battling could serve as another form of art and self expression. Which do people prefer?
Third, I guess, I should throw in California as a potential place to base a region around. There are more biomes in the area than you might expect, and if we do open up the definition of art to include acting, Hollywood is right there (yes, Pokestar studios exists, but more can be done with the concept.) Don't feel super strong about the idea, just feel obligated to mention it.
