I wonder if Mego could still use the old Micro-city building system? Since I read somewhere once that they owned it or bought it from Takara or something due to its failure in Japan. It could be marketed as a building system for 3 3/4" to 4" + scale figures to make playsets with. Since it was technically a building system (yes i know for use with Microman/micronauts) but they could be for anything.
