Special:Badtitle/NS90:Forum:Trope Talk/Difference between Adventure Towns, Planetville, and Wagon Train to the Stars

So what's the diff between Adventure Towns, Planetville, and Wagon Train to the Stars?

So far as I can tell Planetville is Adventure Towns in SPACE, and Wagon Train to the Stars is identical to Planetville. Anything to clarify might help, Laconic pages wanted.
