I would have to disagree that a more complex controller equals a more complex game.
Chess is a very complex game but it doesn't require anything more then moving little objects on a board.
The game you selected seems designed to use the ps3 controller and showing how the Wii controller can't do it.
All this proves is that a game must be developed from the ground up to use the Wii controller, a complex game is simply one that makes you think hard and has lots to do and takes time to do it.
I believe it is based purely on software and not hardware, getting it to work on the Wii requires writing a game that can get around the limitations of it's controller and using it's strengths.
The CPU is good enough for AI, A DVD has enough space for storing the code, The controllers can be used to input commands.
These 3 things are enough to make a complex and deep game for the Wii. There is no reason Something like LOZ couldn't be made open ended.
