I'd like to see pc races expanded a bit in JADE.
Theres quite a few classes in ADOM but only 10 races total and 3 of them are elf-types which in my book really only makes that 8 races.
How about races like:
shadow, drow, faerie, etc.
Or maybe let the pc choose some races that are in adom that you can't pick now - like a goblin or ratling.
