Game Super Black Onyx

Rumor says that the legendary Black Onyx, an artifact that grants eternal youth and happiness to those who can find it, lies within the Black Tower near the town of Utsuro. You assemble a party of brave adventurers and venture into the tower, defeating monsters on your way to the great treasure.

The Black Onyx is the very first RPG made by a Japanese company. It is similar in gameplay to early Wizardry and Ultima games with killing monsters and exploring dungeons, with dark, realistic visuals. You create a party (up to five members) and explore a maze-like 3D dungeon, fighting random enemies on the way. You also meet adventurers whom you can convince to join your party. The combat engine is turn-based.
