It would be nice to actually have a clear description of who are playing as. Even some simple stuff based on possible mutations would add a CRAP TON of immersion. Especially considering that in the majority of texture pacts, characters look the exact same naked unless they have already mutated something like leaves, horns, or tails.
Just something like “a well built man with blue eyes,” or “a small lithe woman with auburn hair,” would be awesome.
