This list also includes games in which the engine is open-source but other data (such as art and music) is under a more restrictive license.

Open-source games with non-free data

Only the game engines 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.{| class="wikitable sortable"!Title!First release!Last release!Genre!Engine license!Content license!Dimensions!Other information
