What's the first game you remember finishing?

First game I finished... Either Super Mario Bros. or Donky Kong on the super Nintendo.
I don't remember which game I finished first. It has been a while since then, but how I sure miss the good ol' days.
I remember when the PS1 came out and playing resident evil.. I got hooked on that until I finished it.. That was probably the next title I finished from start to end. I then ended up playing every resident evil I could get from there on and beating them.. I'm still to this day a big resident evil fan.. Even from the movies and the anime versions.
