I believe firmly in games being the most interesting parts of computers and software. Those games are already in a playable state, but some need far more work to be enjoyable or useful as a teaching material.
Some games uploaded here are in serious need of rework. If you have a game project that you are proud of, have no longer the time to develop it or simply have pity with your project slumbering unnoticed on your computer, feel free to donate your games here. All games need to be GPL-licensed.
