This narrative needs to die. The Wii U's first year was fucking abysmal. I lived through it.
The launch was decent. Then four months of nothing.
Then Monster Hunter, Need For Speed, and Lego City Undercover on the same day in late March. Great timing there, guys!
Then nothing until the end of June, with Game & Wario. That's right, another three months of nothing.
Then nothing until August with Pikmin 3.
Then nothing until September with The Wonderful 101 and Rayman Legends.
Then nothing until October with The Wind Waker HD.
Then nothing until November with Super Mario 3D World.
Wii U's first twelve months were a complete drag. The first nine months of Switch are already better and Nintendo probably has a few more 2017 titles to announce at E3 or before.
Yeah, the system was never able to gather any momentum because of how awful the release schedule was. By the time the heavy hitters were coming out, it was far too late.
