There are a lot of great free games on Linux. Some are even at par with proprietary software. In this post I would like to focus on two great games that will keep you occupied for hours. The graphics are great and the game play is really good.
The first game is a first person shooter. It is called Nexuiz. This is a fast paced shooter that has really good 3D graphics. You also have a lot of guns to choose from and there is a multiplayer game play available once you get tired of blasting AIs.
Another great game for Linux is a strategy game called Glest. It is made by a group in Spain. If you like strategy games than this game is something that you will definitely like and should give it a try.
