"Succesful prison break" is winning and seeing this I realize that I'm not in favor. It would be such a waste of the jail lot and the npc prisoners to become useless after only four sim days.
@Monet11 and @mightysprite You're right, an unsuccesful prison break attempt now isn't mutually exclusive with a succesful one later. That's the route I'll be going.
@GalacticGal Indeed! The prison sits on the lot where the basegame park used to be, so the most likely scenario would be a couple of days desert survival followed by finding the old mine, the cave and eventually the second exit leading to the now abandoned Landgraab mansion. Plenty opportunities for close calls.
