The game engine of Blender faced limited support due to its requirement for games to adhere to Blender's license (GPL) when generating platform binaries. Although there were workarounds available, such as externalizing blend files or using the binary as a loader, these solutions were not practical for most commercial games. It would have posed a significant challenge, particularly if developers intended to port their games to platforms that did not permit such restrictions. Consequently, this limitation likely deterred widespread adoption of the feature, with its usage being primarily limited to prototyping purposes.
