This is my favorite version of alternative race rules that I've seen thus far. It does the best job of seperating species and culture while still letting them be key factors in a character's skillset. I especially like the movement of ability score benefits to culture rather than species. Great work, excited to see what else comes of it, and if I make any homebrew 'races' in the future I'm definitely using this ruleset first.
