The Black Onyx is one of the first traditional role-playing games 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.
The player creates a party (up to five members) and explores a maze-like 3D dungeon, fighting random enemies on the way.
The heroes also meet adventurers who can be convinced to join the party.
The combat engine is turn-based.
About Game Boy Color
The Game Boy Color (1998) added a color screen to the original Game Boy formula while remaining backwards compatible with the entire existing cartridge library. Its colorful, semi-transparent cartridge shells make it a visually distinct platform for shelf collectors, and several late-cycle exclusives — released just before the Game Boy Advance took over — are notably harder to find complete today.
Gamevaro tracks The Black Onyx for Game Boy Color with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding The Black Onyx to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This GBC release dates back to 1984.

Rarity & condition
Only a handful of market sales have been tracked for The Black Onyx, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Game Boy Color titles.
Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
