Oh, yeah... I also made 3D level layouts (mostly puzzle-type games) out of building blocks, LEGO, Playmobil, and whatever else was handy. Lots of castles, bridges, slopes and whatnot for the basic structure, then it'd get lavished with lots of objects the player (usually a parent) had to use in some specific order, like vending machines and buttons and wings and whatnot. Who needs the limitations of paper?
