Man, so many good ones to choose from.
To be honest, I never was the biggest fan of ALTTP. Link's Awakening was more involved in my childhood.
My top 5:
1: Super Metroid
2. Super Mario World
3. Donkey Kong Country
4. Super Mario Bros. 3
5. Teenage Mutant Ninja Turtles: Turtles in Time
Super Metroid has amazing puzzles, interesting backstory, great game play (good variety of power ups), and always kept me curious about the Metroid universe.
