GB came at a time when enthusiasts were screaming for a different layout, they got it and then the shot complaints started rolling in.
If you think GB is a diamond then your probably kidding yourself a little as its not there yet but it is a brilliant linear style game with probably the most gear on it and innovation that stern has brought out in a while. Like avengers it needs tweaking but then is a scream to play... always something going on. Not to mention the beautiful art package and immersive world your given under glass here. definitely this is a premium purchase... pro is just too stripped and changed.
If you think it is a dud.... well you just need to PLAY BETTER!!! as it isn't an easy game... quite frustrating but also very rewarding when you string some shots together with those multipliers going.
