I'm kind of a believer that these types of ideas are partly a byproduct of timing ... that's to say the timing has to be right.
In the early 2000s, 3D graphics were still a new thing relatively and people were still getting "high" off that buzz.
But by 2005-2006 things started to shift and the audience developed a hunger for wanting to get back to simpler gaming and more accessibility.
It wasn't just the Wii that did that, you could see it coming with Guitar Hero also.
Today, I think people have gotten sick of all the casual ware we got flooded with for 5 years and the pendulum is swinging back towards consoles being more of core experiences.
