Gearbox will take you back to court 3D Realms for a rights issue concerning the acquisition of intellectual property Duke Nukem. It is not the first time this has happened and it is probably not the last.
The lawsuit concerns one violation of the agreement signed in 2010, according to which the ownership of the franchise had to pass entirely to Gearbox. In September 2019, however, composer Bobby Prince sued Gearbox for unpaid royalties on his music used in Duke Nukem 3D: 20th Anniversary World Tour, showing that his work had been licensed only for the original Duke Nukem 3D and that it could not be used with the new game without a renewal of the game.
Apogee, a company that owns 3D Realms, was added to the suit between Gearbox and Prince along with co-founders Scott Miller and George Broussard. Apparently 3D Realms would have been notified of the problem in November 2019, but would have refused to pay compensation to Gearbox. Hence the new cause would arise.
As we mentioned, this is not the first legal dispute between Gearbox and 3D Realms. In 2015 there was the one concerning Duke Nukem Mass Destruction, a title that 3D Realms had entrusted to the developer Interceptor without having the rights. In 2013, however, there was a lawsuit regarding the sales of Duke Nukem Forever, closed with an agreement between the parties.
Too bad to see a franchise like that of Duke Nukem be now known more for lawsuits than for published games.
