It's really cool! Regarding the removal of races from character creation: I asked the programmer who wrote that, and it's indeed not possible. ... I'll see whether we can get race presets into a separate mod for future projects, so simply not including that mod would let then you start from a clean slate. But no promises!
Well, in one sense it is a relief to hear that there was not an obvious and simple way to do it that I missed.
Thanks for the information, and any additional controls we could get to remove XML driven content from the game would be great.
