Before, there were only 4 difficulties. Easy, Normal, Hard, and Very Hard. In Mario Party 9, there should be more adjustable difficulties for CPU characters. E, D, C, B, and A. E is the easiest, while A is the hardest. The E, D, C, B, and A CPU difficulties have a slider in it to make things more adjustable. Just like in Mario Kart Wii, there is a place called overall ranking. The overall ranking can be E, D, C, B, A, 1 star, 2 stars, or 3 stars. There should be a section where you get to see all of your records, just like in Mario Kart Wii. There is also an automatic ranking, but he 1 star, 2 star, and 3 star rankings can't be applied to the CPU players, because it would be too much. If your ranking is 1 star or above then the automatic ranking will be A++.
