There are so many things that WiiU had that I miss on Switch (or PS4/XB1):
Miiverse (and private conversations) with drawings, text, stamps, screenshots.
All the marvelous artists on miverse and Art Academy.
The possibility to browse the web privatly and then display it on the TV if I want share with others.
Pictionary games. Great fun for family & friends.
Animal Crossing plaza wich gave me hope of a new AC game.
The possibility to play on the tablet and still be part of the family conversation.
The Fisher Price quality plastic that allowed the tablet controler to fall numerous times on the floor without any damage.
The ergonomic handle of the tablet that made it possible to fall asleep without loosing the grip.
The alluring possibility of asynchronous gameplay that never really materialized.
Mario Maker. How will MM2 work on the Switch? A handheld game only?
The HD Zelda ports: TP, WW.
...and much more...
