Your Collection is more than a list of games.

The cartridge you saved for. The disc you played all summer. The box and manual you finally tracked down. Every copy carries a story. KoreGemu helps you understand its identity, its market evidence and its place in your Collection.

Discover what you own. See what comparable copies actually sold for. Build your private Collection, follow its value and make better-informed decisions about what to keep, buy or sell. Collector progress celebrates the journey, not how much money you spend.

Value a game Start your Collection

Built for collectors. Made for the long game.

We want nostalgia, rarity and gaming history to be easier to discover and understand. Clear identity, visible evidence and a useful Portfolio turn a shelf of games into a Collection you can enjoy, understand and shape. Future collector-to-collector trading is a direction, not a function offered today.

Evidence at the press of a button

KoreGemu Market Value is based on the median of actually observed completed sales of comparable copies. It is evidence-based. The price achieved for an individual copy can vary with condition, completeness, region, timing and market conditions.

We identify the game, platform and release before comparing completed sales. Region, edition, completeness and physical condition matter where reliably evidenced. Unsuitable comparisons are excluded. A robust median keeps individual extremes from dominating; reference sales, sample count and confidence let you judge the evidence yourself. Selected CIB never silently becomes loose. If only physical condition can be compared broadly, we say so and reduce confidence. Too little evidence means no invented value.
