wtf is open-source-games?

This repository is a curated list of open-source video games, organized by genre. It covers a wide range of categories including action, adventure, business and tycoon simulations, city builders, first-person shooters, platformers, puzzle games, racing games, real-time strategies, roguelikes, role-playing games, sandbox games, shoot-em-ups, sports games, third-person games, tower defense games, and turn-based strategies. The list includes two kinds of projects: games that were built from scratch as free and open-source software, and open-source remakes or reverse-engineered clones of older commercial titles. Examples of remakes include open-source re-implementations of classic games like RollerCoaster Tycoon 2, Transport Tycoon, Caesar III, Theme Hospital, and The Legend of Zelda games. Examples of original open-source games include multiplayer shooters, city builders, and space exploration titles. Each entry in the list provides a name, a brief description of what the game is, and a link to its source code on platforms like GitHub, GitLab, or Codeberg. Many entries also note which game engine the project uses, such as Godot or the Cube engine, with separate source links for the engine as well. Some entries include a website link where you can download or play the game directly. This kind of repository is sometimes called an "awesome list" because it serves as a community-maintained reference rather than a piece of software you run or install. You browse it to discover games you might want to play, study, or contribute to. There is no code to execute from this repository itself. If you are a developer interested in learning how real games are built, or a player looking for free games with open codebases, this list is a useful starting point. The entries span many programming languages and engine choices, so there is variety regardless of what technology you are comfortable with. The full README is longer than what was shown.
