Best positive surprise of the Switch

[curl-6]

Lots of great answers! :)

I think third party support as a whole is probably my #1 most positive surprise. After Wii U, and indeed most Nintendo systems since the SNES, I never expected that the Switch would develop such an extensive catalogue of high quality third party titles, from Witcher 3 to Nier Automata to It Takes Two to Doom Eternal and so, so much in between.
