I am attempting my first commecial game. I good at programming but suck at art. I am using some paid for content and some free and have found some content under gpl license that would be very suitable to use in my game but do not want to open source the source code. Although my game uses NO gpl code and I do not want to open source the game I would like to use some 3D models that have gpl license. I don't have the money for a lawyer to answer this question but maybe someone could point me in the right direction? My google searches have not been very productive. Thanks in advance
