I wouldn't call it a "world of good." It's just another reality of some sort. Actually, I wouldn't put a value judgement on either world. The culture of the people that you meet from the other world in Haunted Mesa is pretty authoritarian but it's just one culture in what one must assume is a whole world as diverse in it's people as our is.

There's a third "alternative world" story, it's "Jeremy Loccard" in Lost Treasures Volume One. It seems like it was going to be a sort of a follow up to The Californios.
