IMO The Mickey Mouse sets were poorly designed, the buildings were facads and didn't even have side walls. There were no stories or proper instructions included and the figures were bad. Those sets were good for parts to add to my Fabuland collection though. I hope that if LEGO were to bring back Fabuland they will do it right like they did in the 1980's.
I'm not sure what I think. I mean, Fabuland did have sort of a return with the Mickey Mouse sets . . . not strictly Fabuland, but pretty darn close. I don't think those sold too well, did they? We never saw more than one wave.
