The game had gone through several incarnations and kept getting changed, refocused, and reimagined, as George Lucas himself told the team to make it a Boba Fett on Corsucant game. But art and story details sound like they would have made an impressive game, although almost every iteration detailed in the article would have made an equally-impressive game. Shifting eras, main characters, and even game styles (oh for that GTA-style Coruscant sandbox game!) ultimately doomed the project to development hell, yet the final, unfinished game focusing on Boba Fett going from young and inexperienced through building up his custom armor and skills is an exciting premise with a good-looking cast of characters, and hopefully something positive will eventually come from all that work.
