Destroy All Humans
For campaign purposes I recomend to players to make their characters Humans, half human or partially human (like aasimar or tiefling). If you want to be a nonhuman race your character must be good aligned and/or your character has compelling reasons why you really like humans (possibly one specific human, half human, or partial human, etc. in perticular).
I’m contemplating making the game nightmare difficulty:
If you die, you’re out. You probabily only get one character, for campaign reasons possibly revealed in act 1.
