The Game Is Over
That holds no appeal for me personally. I wish to be able to do things like cast spells, search for undiscovered artifacts, etc. that are tied to the adventures in the game--not the races.Mostly because we wish to be something other than human, we want to be more then we already are.
So, others might want what you say, but certainly not everyone. I've known many players who only play humans--ever. shrug
