I want to remake an online video game that no longer exists and distribute it for free. What limitations do I have regarding copyright law?
The game server was shut down and is no longer available, and the game is no longer being sold. I want to remake a light version of it for fans that can no longer play. I don't intend to charge anything or make any money, and I will be doing all the code and art from scratch, nothing taken from the original game.
The game took place in the Star Wars universe, so I'm also concerned about using terms and concepts like lightsabers, the force, jedi, etc. I want the game to mirror the original as closely as possible when it comes to the mechanics and the naming of things, but don't want to break any laws.
Thanks in advance for any help.
