Before Atari came along, we used to play board games. Clue and Family Feud were my favorites, but Monopoly ruled the household. There are a few board games I never knew existed and thanks to eBay, I've stocked up.
The first game I bought was a vintage, but complete, Charlie's Angels game for $15. I got the original Farrah cover (duh!). I haven't played it yet, but it looks damn cool on my end table at home.
One of the better games I bought has to be the Pac Man Board Game for $10. I know it sounds awful silly to buy a board game based on a video game - but it was too cool to pass up. It comes with big plastic Pac Man and ghosts. You have to gobble up all the marbles before the ghosts get you. I found myself making my own sound effects while playing the game. It's pretty fun to play as long as you don't spill the marbles everywhere half-way through the game.
