I did not expect most of this perfect game, it's been already 45 hours that I'm on this game, I love anyway the world luigi mario nintendo especially, I'm almost at the end of the game, but to finish the 100 % it'll be a little tough to finish above the challenges, I think fighting with some brothers attack are difficult to achieve in "excellent" and also the fighting in Titan mode are pretty hard but there just happens must understand attacks opponents, I found only one defect has this game, I find that it are few small battles to drive up its level or its level while not increasing fast, I'm almost at the end and mario is level 38 and 36 and Luigi to be the rainbow level i understand that you need to reach level 40 to go to book shop in rainbow SnoN but this game is perfect, 3D is excellent, the game also the very good life span, I you recommend this game without problem
