Since I know you've all been dying to hear my picks, and I want to make sure you can all sleep well tonight:
1. Dungeon Explorer - The most fun ever packed into a credit card-sized game cartridge.
2. Anearth Fantasy Stories - Delegated to #2 only by the nostalgic attachment I have for DE.
3. The Legend of Xanadu I - Just started playing this, I'm a good few areas into it, but from the spectacular graphics, cinemas, gameplay and killer PSG tunes this is surely one of the best the system has to offer.
4. Dungeon Explorer II - One of those rare cases a sequel is of almost the same caliber in most areas as it's prequel, and superior in others.
5. Beyond Shadowgate - Love this game. ICOM at it finest.
6. Shape Shifter - Sidescrolling action with RPG elements, a hybrid. Another ICOM classic.
7. Ys III: Wanderers from Ys - Don't believe the lies, this is actually the best Ys game on the Turbo.
8. Wonderboy in Monsterland (Bikkuriman World) - Another platfomer/RPG hybrid. Best console port of the arcade classic save for direct emulation despite the changed boss characters.
9. Wonderboy/Dragon's Curse - Picks up directly where Monsterland left off, literally. Probably technically superior to Monsterland, but I personally like Monsterland better. More platformer/RPG hybrid goodness.
10. Ys I - Part one (Book I) of the series deserves an honorable mention, though it's not as spectacular as many will lead you to believe. Still, a fine game definitely deserving of a top 10 spot.
