Good times
Hero Quest was a lot of fun. I've got my beat up box around somewhere or another, just can't seem to find it. It never directly related to my introduction to DnD, but I suppose that it opened me up to fantasy role playing games.
Speaking of fantasy boardgames... anyone ever play Weapons&Warriors? It was the game where you actually shot plastic balls at enemy troops and emplacements. While it had rules, all the games I remember eventually devolved into rapid fire shooting at the castle (I had the really, really big castle set, with exploding towers and everything).
