Heh...Orici said pretty much everything I believe.
And keep in mind, WW cell-shade type graphics are actually favored over the 'realistic' graphics of
TP in Japan.
I think if there's any problem with the series, it's that it's not fresh enough or difficult enough anymore.
Majora's Mask is an excellent game, as is Wind Waker, and Twilight Princess [though overhyped] is doing very well.
Meanwhile in the 2D world, the games are all quite fun and entertaining, but do lack the difficulty level to make them as cherished as the classics.
