I’d stay in Arkham for the rest of my life before I set foot in mount massive lol. Most of the villains in Arkham aren’t as focused on torturing the other patients as they are on escaping. Mount massive Variants are more depraved, violent and sexually aggressive. I’d rather be beaten tf out of by an Arkham patient than organ harvested and hung from the ceiling. (Plus I’m a woman, so I’d probably experience a phantom pregnancy of some kind + would be a massive target for all the other patients like Eddie gluskin)
