Hi,
Anything media created by TGC can be used in other engines (although why would you want to

).
Non TGC store media is only licensed for use in GameGuru. If you want to use any store media in other engines you will need to contact the artist for permission.
However, in all cases, the developer is responsible for ensuring that all media is protected from ripping and can't be distributed AS IS.
