@Fash-E @Twoinchdestroya @Bead @WashedOutGundamPilot That's after my time.

The LEGO (and off-brand like K'nex) I remember are from around '97-'02 or so.

The only set I can't remember is there was a cheaper version of the Mindstorms. It was a programmable robot, but not as complex as the Mindstorms.
