I've never found a group to run it for.
It's...weird. I like it conceptually, bit it's weird. Looks of random rolls, including for character creation, psychic powers will either be amazing or kill you, and it's a pretty lethal looking system.
If you have a group that's comfortable with running a game in a space prison in a hell dimension, and all of the adult themes that would entail, I'd say go for it. There's a 6? book long adventure path and it's one of the weird random games that I have and want to run.
I own a lot of weird random games.
If you want to get more in depth it should probably be moved to a new thread.
