We're talking beyond the usual types of rule bending such as save scumming (force-quitting the game to bypass the quitting punishment during text events and combat).
I would force everyone's loyalty to be at least 2 or above; I can't stand traitors. I'd also remove the Cleaning Lady, Mason, Octodad, Garfielf, Nimbus Ordeal, Debutante, DSYP, and the Governor Emperor. Suffice to say, I play rare characters for overpowered characters, not joke characters.
