I could probably find that lawyer, although I don't have a game that's actually ripped..I'll just use an example.
Axerob's Way Of the Shinobi Source
This wasn't "given stupidly", it was (as a lot of sources actually are) stolen due to misrepresentation a.k.a fraud. One person pretended to be another and was traded the source, now, as stupid as this may sound, it has also happened to numerous anime sources, one of which being Naruto GOA I hear. Intellectual Property Theft could actually be made into a successful case when you throw the idea of fraud, as well as people charging money for things that you made yourself in the first place.
But I know you won't write me a check, you can't even reply....
