1987 at age 5 for table top. Good ol'DnD. I was the DM's assistant because my older brother didn't want to play with his "whiny kid brother". Read the books, memorized the rules and terrorized my brother as a rather strict rules lawyer. At that point they decided it was better having me on their side of the screen.
First console game was FF for NES. Can't remember when we got the system...
1975 - my cousin ran a game. I went too deep in the dungeon too fast and was swallowed by a Purple Worm. Ahhhh, back in the day when there was ONE dungeon per campaign!
