[DC] I'm a prisoner in Arkham City. What would incentivize me to join, say, Joker's gang rather than Two-Face's? Or Penguin's?

Joker is straight crazy, if you're a member of a rival gang, he sees you as fair game.  He'd think nothing of killing or maiming or torturing you.  If you're in Joker's gang, Two-Face or Penguin wouldn't touch you, they don't want to have Joker turn on them.
