An anonymous reader writes: Linux-gamers.net has posted a well-encompassing, although harsh, comparison of free software shooters. While lengthy, it compares seven open source shooter games. Although the article can be a bit hard to follow at times, few have gone to compare and carefully examine the genre before. The author ranks the games in the following order (best to worst): Warsow, Tremulous, World of Padman, Nexuiz, Alien Arena, OpenArena, and Sauerbraten. In making these choices, it claims claims to use gameplay, design, innovation and presentation as criteria and includes a short history of free software shooters in the introduction.
