Seiken Densetsu - Released in the U.S. on Game Boy as "Final Fantasy: Adventure"
Notes: You might notice Makaitoushi SaGa is part of the "Romancing SaGa" and "SaGa Frontier" universe. Also, Seiken Densetsu is a prequel to the ever-so-popular SNES masterpiece "Secret of Mana," which is really simply Seiken Densetsu 2. A translated rom for Seiken Densetsu 3 is out there somewhere, but since my old computer crashed I've lost it. I assure you that it is 10 times better than Secret of Mana. If anyone finds it, PLEASE let me know!
One more thing: Many of the games listed here were ported to PC. I didn't list them due to laziness and the love of simplicity.
