I went to visit a friend that lived on the eastern boarder of Ohio, and he took me to some AMAZING retro game stores. I picked up one of my favorite (although somewhat retarded) NES games ever for a couple bucks.
Wall Street Kid.
It's pretty much buy and sell stocks in the game to try and make money to impress your wife and move up in the company. Game play is mostly text based with some stills, but good lord did I love to play it as a kid. It's still silly fun to me.
