Wolfire Games, makers of Lugaru and Lugaru HD, claim another developer is trying to pass off their work as their own. The other developer, iCoder, claims they’re doing nothing wrong. The sticking point is the interpretation of an open source license the original Lugaru was published under.
“Matlin cites Wolfire’s May 2010 blog post declaring that Lugaru’s source code was now available to anyone as proof that iCoder could sell the game. (That post doesn’t outline the options as Matlin defined them to Kotaku, but it does encourage developers to mod and port the game.)”
