Finally I got the platinum! Basically, the game is quite repetitive and the platinum cups become easier to acheive after we become familiar with the scoring techniques and with more powerful costumes. However I voted a 7 for it, not because it is challenge, mainly is because I have encountered two glitches. One is the freezing of the loading scene in the online session. One is the Full Wardrobe trophy. Fortunately, these two problems were solved after I redownloaded the 2.01update
