Although it is clear in the final game that Gizmo is the bad guy and Killian Darkwater is the good guy, the original version would have subverted this. The ending would have revealed that, had he been allowed to take control Gizmo would have inadvertently turned Junktown into a flourishing trade center, while Killian, if he was sided with, would have turned out to be a (well-intended) tyrant who would eventually instead run Junkyard into the ground. This was changed to making Gizmo solidifiying his power in Junktown, until he finally chokes to death on some iguana on a stick because it didn't seem black-and-white clear.
