Unfortunately, I had trouble finding players online for MAP and I try to play test things I publish. I switched to OSE, which has a bigger player pool.. As a result I never got to complete it.
I do have rough notes I was using for play testing here if you are interested: https://docs.google.com/document/d/1Jt_tXqANC1ITSQe5s-1SFZJjPJg-L0-DOUJWfdWUyZ0/...
I had the following idea how to do non-humans. Being a non-human is a special talent, called ancestry. The talent itself offers only some ribbon/flavor improvements (e.g. unlimited lifespan for elves, immunity to ghoul paralysis, +2 on searching for secret doors) and since it's a regular talent, it increases the cost of purchasing further talents (buying your next talent costs 7XP for non-humans, vs 6XP for humans). In return the non-human has access to some talents not available for humans (e.g. infravision, immune to charm).
This way non-humans can feel special, but it's costly to be a non-human. This encourages being a human, which keeps the spirit of old games (human centric).
We play-tested these and my players really liked being non-human: I had a goblin, a giant mantis, a dhampir and a dwarf in my ASE campaign.
