Master of the Monster Lair
Nintendo DS · 2008
About this game
Master of the Monster Lair is a dungeon crawling RPG with a different twist, whereas in previous dungeon crawlers the objective is to find the dungeons and monsters to clear them, the player creates the dungeon (or a monster lair in this case) in order to attract the monster and trap it to destroy it.
There are 23 different rooms to customize for the player's Monster Lair.

The story takes place in a small town called South Arc where the nearby forests are harboring monsters who regularly invade the town and scare of the citizens.
This is where the player takes control of an orphan called Owen who is searching for his first job where he encounters a magical talking shovel.
After realizing his destiny, he decides to start digging a lair and destroy the monster infestation.
The view of the game uses the DS dual-screen technology, showing the world in the top screen while the bottom screen will show maps and item menus.
The gameplay is the standard turn-based RPG battle, selecting options from a menu such as attack and casting spells as well as the option to turn and run from the battle.
Players can pick up items and currency from monsters that are defeated in battle and use them to buy new weapons and armor for future battles or even furniture for Owen's house.
There is also wireless capabilities where players can view and exchange dungeons through Wi-Fi.
About Nintendo DS
The dual-screen, touch-enabled Nintendo DS (2004) became the best-selling handheld of all time, helped by its huge and genre-diverse library. Cartridge-based DS games have held up well physically over 20 years, and complete-in-box copies of the system's biggest sellers (Nintendogs, Pokémon, Mario Kart) remain very accessible for new collectors starting out.
Gamevaro tracks Master of the Monster Lair for Nintendo DS 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 Master of the Monster Lair 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 NDS release dates back to 2008.

Market insights
Rarity & condition
Only a handful of market sales have been tracked for Master of the Monster Lair, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Nintendo DS 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.
