About RetroGame — 31,000 Retro Games Catalog
Retro games catalog with an ad-free browser emulator and AI SEO pipeline
RetroGame is a fully working retro-games catalog: platforms, systems and games, each playable right in the browser via EmulatorJS. The core advantage over competitors is a clean, ad-free player, while most sites in the niche are buried under aggressive advertising. What's inside: A database of around 31,000 games with cover art, plus an automatic ingestion parser. Game content is streamed from an external source through the site's own proxy - the site is a catalog with an embedded player and needs no ROM storage of its own. OpenSearch-powered search with ngram autocomplete and a MySQL fallback. AI SEO-description pipeline (Gemini via OpenRouter): descriptions are generated in batches, and only pages with a finished description enter the sitemap - a controlled, safe rollout of tens of thousands of pages into the index with no thin-content risk. Full SEO: JSON-LD (VideoGame, BreadcrumbList), canonicals, OG tags, paginated sitemaps. Laravel, Filament admin (games, platforms, comment moderation), Docker. Retention features: favorites, comments, recently played, similar games. Revenue model: the "play [game] online" long tail leads to alternative ad networks, donations or premium features. The retro-gaming niche is stable and growing, and 31k content pages carry near-zero production cost. Stated openly: game content comes from an external source and the niche carries copyright considerations, which is why monetization is built around alternative networks and donations rather than AdSense. All details discussed openly before any deal. The buyer receives: code, domain, database, the parser, the configured AI pipeline, and migration help.
Next step: <p>Accelerate the description pipeline so all 31k pages finish entering the index, and put sitemap generation on a scheduler. Mirror critical assets (covers, metadata) locally to remove the external dependency. Monetize via alternative ad networks plus a donation or premium tier - the retro audience is loyal and donation-friendly, as niche Patreon projects show. Retention features (accounts, collections, ratings) are the natural next build.</p>
