For a while, I've had this odd relic lying around. It's a pack of Nintendo Game Pack cards, made by a company called Topps back in 1989.
They're not exactly trading cards, but more of mini-games in card format. You scratch off bubbles to "win" a fight of some kind, modeled after any of the then-popular game franchises. Thrilling!
Unlike video games, you can't try again if you lose. By playing at all, you also lose the cards' collectibility value... if there ever was any.
