I wonder if they over designed it and lost something along the way. When you focus so much on making it perfect and believe it so much, you can lose sight of the important things. It would be surprising if Bungie miss the fun aspect.
God, I can't wait till E3 or the beta comes out so people make any proper judgments about the game.
So far, it's assumptions over footage which is boring for some people. Granted, the official footage wasn't any better either.
