The Blender License says that games you create with blender are not covered by their license, however, any "data" inside "standalone" games are subject to the license.
Games created in Blender (.blend files) are program output and therefore not covered by the GPL. You can consider them your property, and license or sell them freely. With stand-alone games however, any data that is included inside the actual stand-alone executable is covered by the GPL. If this is a problem then you should set up the stand-alone player so it reads from external .blend files. A common practice is to include a “please wait, loading…” scene in the standalone, and read level files externally.
As I understand it, all software is technically "data", so I was wondering what exactly this was referring to. Does it refer to the parameters of the object, like, say, for example, the coordinates of a cube's vertices? Maybe the height of a character, the high score of a player?
Thank you for your time.
