Let's Play what?

I want to begin recording a video Let's Play of an older video game. What's great about a Let's Play, it's a chance to relive a video game that may not be very familiar or overplayed. I plan to make my first Let's Play for the Nintendo game "M.C. Kids" but I am open to suggestions for another game. Only rule that I know about in terms of making a Let's Play is to wait six months for a new game, but M.C. Kids was made in 1991, so I think I'm safe :)
