@corfiot @7 @LukeAlmighty do you know how there are deaf people who refuse cochlear implants because this would exclude them from the deaf culture? Probably same thing.
I sort of understand why this might work IRL, but in fantasy or sci-fi worlds where there is all kinds of magic, including character resurrection, golems, androids, nanobots, and what not, disability just screams intent on the part of the writer. And while it might be interesting if disability made for an interesting character trait -- imagine a mage who wouldn't have his eyes healed because he can "see" the world around him through magic or a cleric of a blind god who blinded himself as a part of his cult initiation -- disability just for the sake of disability ruins all immersion and fun.
For one, in my beloved Pathfinder: Kingmaker, one of the characters blinds himself at some point of the game depending on the player's choices and alignment. And this really does make sense from the plot point of view. Of course, he receives all penalties associated from this act (but funny enough, he still has better Perception than the stupid paladin chick because she's just a total retard and her INT is lower than that of a goblin, I kid you not).
Now, I glanced through those modules quickly, and there is literally nothing in them that would make it interesting to play a character in a wheelchair. You can do it, of course. But there is just no reason to.
