There Star Wars droid factory was basically a play set for the jawas at least in theory. It was actually a fun robot construction toy. You could build several robot or droids including R2 D2, though I never really did. I liked making my own weird droid creations and seeing how strange I could get. It was really a really a well put together toy for the time. Everything had a spot and most things plugged right in. There was very little mess which my mom liked and I could take it anywhere in the house which I liked.
IGN article that list several other Star Wars playsets. I actually had the Death Star Space Station set as well. It was pretty fun after you got it out of the box and built. The trash compactor was fun but you quickly lost foam blocks.
