At least once a week I like to report video games and online games, always free and always beautiful. After all, the world of videogames is an important part of computer science and not only children or obsessed ones play with it but all those who work on the computer, be they professionals or technical phenomena. In other articles I was reproached for having always reported online or free games to download only for Windows, forgetting that there are also minorities who use Linux or Mac.
To make a level playing field, below I have compiled a list of (for now) opensource games that can be downloaded and installed on both Linux PCs, Macs and Windows. The peculiarity of these games, listed here in alphabetical order, is that they are not only free to download, but they will be free to play forever, precisely because they are open source, not belonging to profit-making companies and developed by volunteers.
