I just noticed that we had two different Micronauts threads in here, so I merged 'em up!
Micronauts was one of the few other toy lines I used to collect as a kid, aside from Star Wars. Really enjoyed this line, but unfortunately they were all lost to the family garage sales of the mid-80's (unlike my vintage SW collection).
I had that big Battlecruiser set, that little "box" command center set, the Speederbike thingees, a bunch of the loose figures, and various other pieces. I was in no way a completist with this line like I was with Star Wars though. But it was still fun to mess with, to pass the time between SW figure releases!
