Open Source Game Development: Qt Games for KDE, PDAs, and Windows starts with a review of game design and walks the reader through Open Source game development using Qt and KDE. From there it moves on to cover topics such as Canvas Games (2D), OpenGL (3D), graphics & sound, pathfinding, AI, particle effects, math, and physics. Open Source games are not always known for their high-quality graphics. This can often be caused by the games being designed by committee in that many different people may work on the graphics, even in the same areas, which can cause plenty of inconsistencies. Open source innovations have evolved rapidly in recent time, and this has not only helped the corporates to move ahead but has also helped the gaming industry to rise. Talking about the developers, the rapid advancements, the skyrocketing popularity and the advent of open source game engines has put them in a win-win sit.

Open-source games with own but non-free content[edit]

Only the game engine in this table are developed under an open-source license, which means that the reuse and modification of only the code is permitted. As some of the games' content created by the developers (sound, graphics, video and other artwork) is proprietary or restricted in use, the whole games are non-free and restricted in reuse (depending on the content license). The motivation of developers to keep own game content non-free while they open the source code may be the protection of the game as sellable commercial product. It could also be the prevention of a commercialization of a free product in future, e.g. when distributed under a non-commercial license like CC NC. By replacing the non-free content with free content, these games could also become completely free. In practice, many projects include a mixture of free and non-free own content.
