+Games is a GNOME 3 application to browse your video games library and to
+easily pick and play a game from it. It aims to do for games what Music
+already does for your music library.
+
+You want to install Games if you just want a very simple and comfortable
+way to play your games and you don’t need advanced features such as
+speedrunning tools or video game development tools.
