What is PlayDeb.net?
According to their “About Us” page:
PlayDeb is an unofficial project with the mission to provide the latest open source and freeware games for the current Ubuntu Linux release, in an easy to install manner.
The PlayDeb repository extends the official repositories by providing latest versions and new games. Unlike the official packages, PlayDeb packages do not have a predefined release schedule – new game versions are provided as they become available from their authors.
tl;dr: This site makes the latest games easy to install in Ubuntu.
