Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Anyway, I am confused about Sauerbraten. On wikipedia, it stands as open source. On their page, no mention of open source. Not that I like the game though, but I wanted to know for sure if it is open source or not
Per their web site: If you wish to use the Sauerbraten source code (ZLIB license) in any way, read the src/readme_source.txt file carefully.
The zlib License is a permissive free software license which defines the terms under which the zlib and libpng software libraries can be distributed. It is also used by other free software packages, e.g., on SourceForge.
The zlib License has been approved by the Free Software Foundation (FSF) as a free software licence, and by the Open Source Initiative (OSI) as an open source license. It is compatible with the GNU General Public License.
The license only has the following points to be accounted for:
* Software is used on 'as-is' basis. Authors are not liable for any damages arising from its use.
* The distribution of a modified version of the software is subject to the following restrictions:
1. You must not claim that you wrote the original software,
2. Altered source versions must not be misrepresented as being the original software, and
3. The license notice must not be removed from source distributions.
Note that the license does not require source code to be made available.
Surely no mention of being open source or under GPL but is freely available and can be used and played of any purpose. It can also be redistributed but can not be changed or used as an engine.
But if Chrome can make it to the list then this game can surely be there for it is available for free and can be installed on linux.
It can also be redistributed but can not be changed or used as an engine.
This is incorrect.
Saurbraten engine is opensource. It can be used, modified, and redistributed. But content used in game is not opensource. If you want to create your own engine based on saurbraten, you'll have to use your own content (all models/levels/sounds/textures):
If you want to produce new content with the sauerbraten engine, you have to be aware that the source code may be Open Source, but the game and the media it consist of have their individual licenses and copyrights. This means that you have roughly 3 options:
* You may produce new content for the sauerbraten game, for example as a "custom map" (.ogz/.cfg/textures etc). Contributing to the original game is most welcome, and the most productive way of working with Sauerbraten.
* If you want to create your own gameplay beyond what you can do with a map, the best way to do this is as a "mod" (same as above, but with new executable that incorporates your gameplay), that requires an existing install of sauerbraten, and installs only the new files you created in parallel to the existing files.
* If you insist on making a standalone game based on sauerbraten, do realize that only the sourcecode is yours to use freely (if you abide by the ZLIB license, see below), not the media. You CANNOT simply redistribute the entire sauerbraten package with your modified files, as the majority of game media is not yours to use freely (it is made by many authors with a variety of licences and copyright restrictions). Unless you have explicit permission from the authors, or the readme says explicitly "may be used for any purpose" or similar language, it will be illegal to include in your standalone game based on the sauerbraten engine (you may not assume that just because a file has no explicit license, that it is free of copyright). Therefore, if you wish to produce a standalone game, be prepared to make many of the maps, models, textures, sounds etc from scratch yourself.
Same applies to warsow, tremulous, alien arena, world of padman, urban terror. The only two fully 100% open games are Nexuiz and OpenArena. 100% open is a game, which has it's both content and engine free (in open source sense by FSF). If the logic would be considering the game open source even the media is not, then all quake games are open source then.
