Read this article about the use of disability in games by FanOnyx on Writing Alchemy:
Half of my favorite games growing up committed the sin of rewarding disability with more character points—Deadlands and Champions—while half never even mention disability during character creation—D&D and Palladium.
I have two story games where players can or must choose negative traits: neither include disability* among them, and both invite players to round out their character’s definition with any identity they like. This gives players the option to create disabled characters, without rewarding or punishing that choice. On the other hand, these games fail to explicitly invite disability as a character trait, and offer no guidance how to do so respectfully. I’ll try to do better with that.
(Upon closer inspection, one includes ‘Injured’ which has a lot of overlap with disability and implies disability. Still, it is handled neutrally; there is no inherent advantage or disadvantage mechanically.)
