bobeff/open-source-games ? reverse-engineered prompt

Build me a simple project that curates open source video games and open source remakes in one easy place. I want it to feel like a clean community maintained list, organized by genre, with sections like action, adventure, business and tycoon, city building, first person, platformers, puzzle, racing, real time strategy, roguelikes, role playing, sandbox, shoot em up, sport, third person, tower defense, turn based strategy, and other lists.

Each game entry should show the game name, a short plain English description, a link to the main site when there is one, a link to the source code, and engine info when that matters. Keep it easy to browse with a table of contents and readable formatting.

Please make it easy to maintain from one main source, and add any small helper scripts needed to keep the list tidy or updateable. Also include a short contributing guide so people can add games in a consistent format. If you need details, look up current docs or examples online.
