It was either the classic Duck Hunt, or Tarzan on the PS1. I can't remember which came first, but I know that I used to play Duck Hunt whenever I visited that aunt's house. We still pull it out once in a while when we have family gatherings. But Tarzan was my first game on a home console, and I don't think I ever beat it. We never had a memory card, so I didn't finish any of my games as a kid. Probably for the best, though: they never got boring for me.
