RetroGame Collection is a community-built database and collection-management service for people interested in classic video games. It helps users record and organize their collections, document proof of ownership, and share their holdings with others. The site brings together information on game software, gaming hardware, and related media, making it a central place to explore and track retro gaming items.

Users can search the database and narrow game-software results by platform and other available criteria, including genre and ownership status. Its platform listings span many generations and manufacturers, from early home systems such as the Cassette Vision, SG-1000, and MSX to consoles including the Famicom, Mega Drive, Super Famicom, PlayStation, Nintendo 64, and later systems. Manufacturer filters cover a broad range of publishers and producers from Japan and around the world. Designed to grow through community contributions, RetroGame Collection supports both personal cataloging and the discovery of items recorded by fellow collectors. It offers a focused resource for documenting and sharing the history of video game collections.
