Ravenous Bugblatter Beast of Traal
Any system that mandates rolling up character creation. Optional? Fine. Mandatory? No.
Curious on the level of detail. Does this encompass older versions of D&D, with random ability scores and HPs/level? Or is this just at the level of something like original Traveler where your character could die during character creation? Or something in the middle like 1st ed Warhammer Fantasy Roleplay where your career was also random on top of just about everything else, but you couldn't actually die. (Though you could be a ratcatcher).
