Under the category of "more" came this most unusual and interactive of the Kenner Star Wars play sets, 1979's The Droid Factory. This industrial droid production center was unique because it was not a reproduction of a set or ship, or even a landscape (like the Land of the Jawas Playset...). Instead, it was an original and very cool setting not seen in the film, one in which you could build your own version of R2-D2. As a child (and even before The Empire Strikes Back), I appreciated this -- it was good for the burgeoning imagination -- because an original toy like the droid factory indicated that there was a larger world "around" Star Wars than the one we saw in the movie.
The Star Wars Droid Factory came in a large box complete with a beige "factory base with swivel crane" plus "38 robots parts." Essentially, you could "build up to 5 different robots at the same time," "make hundreds of different combinations," and just have a hell of a lot of fun with the "interchangeable robot parts." These factory-constructed robots were the same scale as the other figures, so kids could experience the immediate gratification of landing their newly-built droids into the action with Han Solo, Hammerhead, Jaws, Greedo, Blue Snaggletooth or anyone else.
The Kenner Droid Factory also came with a neat "Droid Maker Blueprints" set which offered instructions for building "the 5 basic droids." These were: the Mechano Droid, R2-D2, Tracto-Droid, Quad-Pod Droid, and Rollarc Droid. The last page of the booklet offered details on how to build a goliath "Monster Droid." Clean-up after play was easy too, as the booklet thoughtfully informed parents: "Each part has its own place in the Base. When you are finished playing with your DROID FACTORY, put all the parts back just like you see it here."
The only drawback to this great vintage toy: there was no way to build Threepio. Yep, Anakin could do it on Tatooine, but you can't do it with your Droid Factory! Clearly, that's a huge oversight in an otherwise very cool toy.
