Ah, Star Wars … they got it absolutely spot on in terms of merchandising for us kids back in the day. I remember my AT-AT fondly, and my Snowspeeder, X-Wing, Y-Wing, Landspeeder, Scout Bike, Dagobah "System", and all the other stuff. Plus the memories of building "sets" … those were the days …
Awesome vid too.
EDIT: I still yearn for the day I can buy (invest/spend money on/waste money on – tick as applicable) a full complement of original Star Wars figures with all accessories, etc and stick them in a cabinet … and have another full set still in their packaging. Sad?
