Either Snoopy's Silly Sports Spectacular or Back to the Future NES. As a kid, I only got a game or two a year, so I had to play them no matter what. While the Snoopy game wasn't terrible, I think I was a little too old for it when I got it. As for BttF, well...it was made by LJN. I didn't know what that really meant as a kid, but now I do. Still, I played that game to death. The "walking" levels were just so terrible and boring. I just kept playing, though. Ahh...to be 10 again! :-)
