Rumpelstiltskin's Labyrinth of the Lost
I'd ply this game with my younger brother on our dad's Compaq computer. It was a lot of fun, and taught us a lot of useless facts about the world. It's a very fun game with a good narrative plot that makes the stakes of the otherwise disconnected gameplay seem more important.
I'd love to see this game booted back in my computer, even though I will never be able to play it with my brother again.
