Remember when the Wii U was aiming for the "core gamer"?

[Leynos]

Wii U didn't support modern game engines at the time like Cryengine or Unreal. (Sonic Boom was forced to be on Wii U despite using Cryengine and it wasn't supported on Wii U) It used a CPU from the year 2000. I think Nintendo used their API and successor to the Gamecube/Wii API with GX2. 2012 we know devs were wanting to move to more standardized API and hardware. Wii U had neither. Switch does.
