The novel I have always dreamed of writing is actually a fan fiction set in an old videogame franchise. The videogame in question has almost zero plot, or storyline, but I'm fascinated with the setting and characters. The franchise has been dead for nearly 10 years, but the development studio that made the videogame is still active. If I were to build a resume, and earn the credentials of a serious author, would they allow me to use their trademarks? I have been doing a lot of thinking about writing this project under a unique title. Could the author in this example get in trouble: - Say I wanted to write the book version of Grand Theft Auto 4, but wasn't allowed to use any of its trademarks. - Instead I change the city where the game takes place to another fictional location. - I DO NOT use any names of characters in GTA4, and write characters that DO NOT have similar traits. - The plot line has no connections to that of GTA4: different character interactions, different plot twists, different scenes, different ending. Would that be fair or foul? Would I have to worry about a lawsuit, or just accusations that I wrote something just like a videogame? I wouldn't be ashamed to say I used a videogame as inspiration seeing as its a different form of media. (a lot of what if's I know And now that I think about it 'Grand Theft Auto: Vice City' is extremely similar to the movie 'Scarface' as a matter of fact, the developers of the game admitted this.
