11. Star Wars: The Force Unleashed 2
You had one job: Give us much more physics-based mayhem. Long before George Lucas would sell off his favourite cash cow and allow other people to expand on the story, he would have a hand in developing 'Starkiller'; the naffest-named hero this side of Blobert. Taken as canon, the first game told the story of Darth Vader taking a random child under his wing who's powers he sensed from an early age before raising them to become his apprentice - although in the end the two of them would end up taking each other on regardless. It was a fantastically enjoyable third-person romp through a few memorable locales that took the very idea of having force powers and cranked the dial past 11; you could actually pull a Star Destroyer straight out of the sky with your bare hands at one point. So what happened for the sequel? How did they attempt to top this universe-expanding narrative and the accompanying setpieces? They released five very short missions that reeked of initially being downloadable content for the first title, as a fully-priced product. It was one of the laziest examples of game design seen in years, and when the levels themselves only had a few moments you'd want to bother to repeat, this was traded in in the thousands within weeks.
