Super Mario Bros. - obvious choice
Chrono Trigger - a user-friendly RPG that's not too complicated but still demonstrates how awesome the genre is
Super Metroid - easy to pick up and play but difficulty ramps up quickly. Best 2D action game ever made
The Legend of Zelda: Twilight Princess - pefection of the OoT-style, 3D Zelda. You have to admit if this was the first Zelda you ever played, it would be your favorite.
Metroid Prime - pinnacle of gaming (IMO).
