80's for me too, I had a Vic 20, friend of mine had a Commodore 64, hadn't seen or heard from him for a few days, during school holidays, so went over his place to find out what was up. There he was playing this game with graphics like I'd never seen before, I mean the 64 excelled at sprites, but this guy was playing a game with 3d graphics, sure just hidden line unfilled vector graphics (didn't know it was that back then), but WOW!!! So after much much begging and much hard labour (for a kid) my mother bought me a C64 and the game....
