We loved micronauts, and star wars toys, and all kinds of models, anything from sci-fi to Dukes of Hazard to WW1 thru Vietnam era. Then we got into Metagaming Microgames, like Ogre, GEV, Sticks and Stones, lots of others, and also an RPG called The Fantasy Trip. We then started playing Traveller and Gamma World too. [insert nerd alert here]
That's a fairly good nutshell version of my childhood toys history as I recall.
