In no particular order:

Fatal Labyrinth (Quick afternoon-filler)
Golvellius (Like TLoZ but better)
The Legend of Zelda: A Link to the Past (I taped myself playing it, yeah)
Phantasy Star II (smurfing Earthlings)
Shining Force (I love Sega Channel)
Shining Force II (Oddler)
Star Ocean: The Second (Best) Story
Tales of Destiny 2 (Best story I've played)
Ys (Freaking music, so eerie and catchy)
