To throw in some fresh ideas, we also decided to make the races based off of animals instead of the standard Tolkien fantasy fare. The ones I know for a fact that Im having so far will be human (but not the typical ones, almost caveman-ish, a bit more primal at least), lizard, cat, bird, and fish. But with these new races, Ill have to establish relationships and cultures to an extent. I wont be able to assume my audience automatically knows how the lizards and cats will interact, like I could with dwarves and elves. That will take some extra time, but it will be worth it, I think.
Other than that, all is well and proceeding as planned. :D
