I fucking love the game.
I'm 21 and Got brain age 2 yesterday. My brain age right now is 32, real age 21. My age on the first one is 54. I love the new piano feature and it shows in the book that You get to some what play dr mario in some form. Looks like regular Dr mario though. Still the best game for sudoku. 2 is working my brain a lot harder than first one did. Wish I could have got the specail ds though.
