Pre-GameBoy Color days...what was the best?
No real order...
1. Zelda: Link's Awakening
2. Metroid 2: Return of Samus
3. Super Mario Land 2: 6 Golden Coins
4. Gargoyle's Quest
5. CastleVania 2: Belmont's Revenge
6. CastleVania Adventure
7. Contra: The Alien Wars (Nice port of the SNES)
8. Donkey Kong (The 101 level...which later was remade as "Mario Vs. DK" on GBA recently)
9. Mega Man V (Most original of the GB series I thought)
10. Tetris
