GameDNA vs NostalgiaDB

GameDNA is a commercial video game database covering titles from 1971 to today, with tens of thousands of games across major platforms. Basic records include titles, genres, player counts, publishers, developers, and descriptions. Premium adds barcodes, product IDs, Amazon ASIN, eBay EPID, pricing data, and affiliate-ready mapping. The Corpus tier supplies AI training data modeled from real-world game materials, validated for model use and accompanied by provenance data. New titles, identifiers, and pricing are added regularly. Delivery is available through Datarade, Snowflake, and Databricks marketplaces, or by direct and API delivery on request. Shared-dataset queries and versioned snapshot exports are available. Commercial products and platforms require a separate written license agreement. Pricing depends on tier, license term, and use case, with a quote required and no fixed prices shown. GameDNA Telemetry is still in development, with a waitlist offered.

NostalgiaDB is a free metadata database for retro game releases spanning 1977–2005. Its archive covers titles, platforms, release dates, ratings, cover art, and descriptions across 45 gaming platforms. Natural-language search helps locate games, while a GraphQL API provides access to releases, ROMs, systems, reviews, and media; API queries require a key and are limited to six levels of depth. Free SQLite database archives can be downloaded with a free registered account, and their presigned URLs remain valid for 15 minutes. Registered members can use the browser-based Play portal to run their own locally stored ROM files in a client-side emulator sandbox. Play requires a Chromium-based browser such as Chrome, Edge, Brave, or Opera. The portal says game files are read from the user’s device and are not uploaded or transmitted to Nostalgia Lab servers. Centralized sign-in supports Google, Microsoft, and Discord. Nostalgia Lab describes the platform as a non-profit preservation project funded by voluntary donations and serving researchers, historians, developers, and enthusiasts. It says it does not sell user data, serve targeted ads, or store payment information.
