[QUOTE=darthmob;195974]I’m slightly confused. Will the sourcecode from the game or from the engine be released?
For example Q3: The game’s sourcecode is available for download but that has nothing to do with the engine idtech3, right?[/QUOTE]
The quake 3 gamecode and ET gamecode are already open source. But they code wont run on its own. It needs to sit on top of the quake 3 engine (id tech 3). This also means that there are certain aspects you can change with the game code along e.g. the engine handles graphics etc.
If you had the engine code as well you could make any changes you want. However you would not be able to run it as a mod. It would have to be treated as a stand alone game. So I doubt its going to really touch the current ET scene
The quake 3 engine is already open source so its possible to actually compile the engine and game code and make a full working version of quake 3. And since you have the entire source you could make any changes you are able to implement.
Although ET runs on the quake 3 engine some slight modifications were made to the engine, meaning that you can use the quake 3 engine source. Even though ET does technical use the ET source
