Wizardry: Proving Grounds Of The Mad Overlord
Game Boy Color · 1981
About this game
The Mad Overlord Trebor was once only power-mad, but went off the deep end after he acquired a magical amulet of immense power, only to have it stolen from him by his nemesis, the evil archmage Werdna.
Werdna, not quite sure how to use the amulet properly, accidentally causes an earthquake which creates a ten-level dungeon beneath Trebor's castle.

To avoid looking silly, Werdna declares the dungeon to be the new lair for him and his monster hordes.
Trebor, not to be outdone, declares the labyrinth his new Proving Grounds where adventurers must prove themselves for membership in his elite honor guard, and incidentally retrieve his amulet in the process.
The first Wizardry was one of the original dungeon-crawling role-playing games, and stands along with Ultima and Might & Magic as one of the defining staples of the genre.
The player generates and controls a party of up to six different adventurers, choosing from five races (humans, elves, dwarves, gnomes and hobbits), three alignments (good, neutral and evil), and four basic classes (fighter, priest, mage and thief).
These can later evolve into elite classes (bishop: priest with mage spells; samurai: fighter with mage spells; lord: fighter with priest spells, and ninja: fighter with thief abilities) if they meet the necessary level requirements.
After outfitting the party with basic weapons and armor, the player sends it into a 3D vector maze-like dungeon to fight monsters in turn-based combat and find treasure.
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 Wizardry: Proving Grounds Of The Mad Overlord 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 Wizardry: Proving Grounds Of The Mad Overlord 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 1981.

Rarity & condition
Only a handful of market sales have been tracked for Wizardry: Proving Grounds Of The Mad Overlord, 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.
