I would personally call NSMB the biggest disapointment. I was expecting a great throwback to the classic 2D Mario platformers, but instead the platforming was bland, Mario's movement didn't feel right, and the new graphics and music were lame. As for MPH, I was sorta disapointed, but feel similarly to Ian regarding it.
Also, while I certainly dug TP, I think calling it without a doubt the best Zelda ever is going a little overboard, personally. Also, I've already complained about its music, so needless to say I don't think your praise of it was deserved. :b
