Here is a big list of this generations cancelled games from game informer  
  
  
Sometimes games don't make it to the finish line. Sometimes a game's cancellation is a huge disappointment. Sometimes, we don't even know a game exists until it gets cancelled. Other times a game gets canceled so early in development that we never even hear about it (these obviously won't be included on the list). This is our evolving database of all the known games that have been cancelled for the PlayStation 3 and Xbox 360. Many of the games on this list haven't received official cancellations, but the evidence points to their disappearance. If they suddenly surface we will be more than happy to remove them from this list. If a game is suddenly cancelled, however, you can bet it will show up here.
