Open-source games with own but non-free content
While the games in this table are developed under an open-source license, the reusage and modification of only the code is permitted. As some of the games' content (sound, graphics, video and other artwork) is proprietary or restricted in usage, the whole games are non-free and restricted in re-usage (depending on license). The motivation of a developer to keep the own content non-free while he opens the source code is most often the protection of a game as sellable commercial product. Sometimes the motivation is the prevention of a commercialization of free product in future, e.g. when distributed under a CC NC license.
