6. Battle of the Sith Lords
This could have become a reality back in 2011 as Lucasfilm was working with video game developer Red Fly Studio on a game featuring the Sith Lord. This was named Battle of the Sith Lords, and would have featured Maul at its center. The story would also have involved a female Sith named Darth Talon, who would have teamed up with Maul against an enemy Sith army. Sadly this never came to be – communication between Red Fly and Lucasfilm broke down in the wake of Disney’s acquisition of Lucasfilm. The Game Informer video below, though, gives an idea of what could have been.
