A young man named Shion vowed to defeat them and make his land peaceful again.
Wonder Boy In Monster World is the third game in the Monster World spin-off series, originally known as Wonder Boy 5: Monster World 3 .
It puts the player in control of Shion in his quest to save Monster World from the evil hands of BioMeka.
It controls like a standard platform game - run, jump, and kill enemies.
The game has light RPG elements such as talking to townsfolk, collecting money to buy items, upgrading your life, and equipping a variety of armor and weapons - staying very close to the Zelda format.
You can save your game to continue your quest at a later time.
About Sega Game Gear
Sega's Game Gear (1990) was a technically capable handheld competitor to the Game Boy, notable for its full-color backlit screen — a real advantage at the time, offset by famously poor battery life. Its commercial underperformance against Nintendo's handheld means smaller print runs overall, and complete, well-preserved cartridges (the plastic shells are prone to yellowing and cracking) are a genuine niche within retro handheld collecting.
Gamevaro tracks Wonder Boy for Sega Game Gear 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 Wonder Boy 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 GG release dates back to 1991.

Market insights
Rarity & condition
Wonder Boy has a steady sales history on the tracked marketplaces, meaning enough copies circulate to establish a reliable market price.
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.
