I watched the video and do kind of agree with him. Honestly, the WiiU was a catastrophic failure and many of its crown jewels deserve a second chance.
I would certainly be interested in a Platinum Games collection, and I think a re-release of DK Country Tropical Freeze would be a great idea and the game would be a great fit for portability.
I don't know about the Mario Galaxy games though, they would look amazing, but they were built for the Wii Remote and even Dolphin gameplay with a Mouse cannot emulate the feeling of catching those Star Bits.
This of course does not mean they would replace new experiences, but rather that a wider audience would be allowed to play these overlooked titles.
