Quake III Arena, soon referred as Quake 3, Q3A or simply Q3, is a first-person shooter published by id Software in 1999.
Its engine, known as id Tech 3, supports OpenGL graphics (and specific support for the "3dfx Voodoo" cards, popular at the time).
Quake 3 and another game released that year (Unreal Tournament) were different from previous FPS because of they didn't have single player "story" game. Previous games had a "deatchmatch" multiplayer game mode, but these two games focused themselves on this game mode. They were a success.
In Quake 3 you can fight against human players over LAN or Internet, or you can play offline against computer-controlled players called "bots".
The game supports additional maps and character models... and entire "mods" that can change various aspects of the game. Many of them have been created by fans. id Software itself created a commercial mod called Team Arena.
Games derived from Quake 3
Until 2005, various commercial games used licensed (and modified) versions of its engine (for example, Star Trek: Elite Force, or Star Wars: Jedi Knight 2).
On August 19, 2005, id Software released the source code of the game under the GNU General Public License, allowing programmers to use it for free.
So, ioquake3 was born. ioquake3 uses a modified version of the id Tech 3 engine, resolves some bugs and adds various features, like support for IPv6. ioquake3 source code is under GPL, and you can download the installer for free...[1] but to install it, it needs the textures, maps and 3d models from the original Quake 3, and they are still under copyright of id Software (only source code is free). This means that you must buy Quake 3 to be able to install and use ioquake3, and you can't share freely the whole thing.
Since ioquake3 source code is free, it has been used to create OpenArena. OpenArena is totally stand-alone (you don't need the original Q3A) and free: all copyrighted material has been removed, everything has a free license. So, you can play a game very similar to the famous Q3A and use the improvements introduced by ioquake3, at no cost.
Compatibility with additional stuff designed for Quake 3 with OpenArena

You can use additional characters, maps and mods designed for the original Quake 3 Arena inside OpenArena. But some of them could have some problems, for example caused by missing textures, missing maps or missing bots. Please refer to ModCompat page for additional info. In general, mods designed for Q3A v1.27 or later should work.
