I don't see a problem with adding new official races (there are quite a few already). I'm looking to see if we can make 'races' more unique and meaningful with Maverick for the re-work. Although the game uses specific races, it is likely that I would create major race species fitting with the game's current pattern - humans, beastkin,... insectoid, plantoid, slime-moid, dragon?, rodent (for mousekin)?
In these species groups would be specific 'races' - wolfkin, foxkin, etc. Then they could interbreed giving us the half-breeds
