Before the Wii U even launched I had the idea that it wouldn't do good based on these reasons:
- The casuals wouldn't be there: because they are people who already don't game that much, and
are already pretty complacent with the Wii they already have.
- Didn't stick with the motion controls and went with a new type of controller altogether
which would have them developing another "under-powered" system to keep the price low enough.
- During the Wii's generation, a lot of the games it received from 3rd parties were shovel-ware or low budget
and this was a system that had a larger install base.
