Hah, so I'm not sure why I ordered that 200GB micro SD card. So far there's been no need for it. Otherwise, though, we have really enjoyed the system.
My son has played Mario Odyssey to death, and has returned to it now for the new Luigi balloon world stuff. He's a pro at jumping and getting to hard places so it is right up his alley. He has already gotten all the moons/stars in the game prior. I could never master that hat-throw-jump that you need to get to a lot of them so I stopped playing after beating Bowser.
I've been slowly playing through Zelda and that game is even better than I thought it would be despite all the game of the year and perfect score hype. So that's saying something.
We cracked open Mario Kart, too, and my son enjoys playing that online. The shine is off Mario Kart for me though. I really enjoyed it on the Gamecube, but each iteration after that has held my interest for less and less time.
I still have Xenoblade Chronicles 2 and Disgaea 5 on the backlog. And I regret not getting that cheap copy of Mario + Rabbids around Black Friday. Will look for one now I suppose.
One thing I don't like about it are the need for the expensive controllers. We still break out the Wii U for Smash Bros. and while I'd like a Switch version what I will not like is that fact that I can't use old Wii remotes with the wired gamepads on them. Those are perfect to use so our family can get into 4 (and sometimes 6) player Smash sessions. Right now I only have 2 controllers for the Switch (the original Joycons and a single Pro controller). I'd be hard pressed to spend $140 for 2 more Pro controllers just for occasional Smash Bros play. I could maybe try a wired controller but I see the Switch getting yanked off the entertainment center with my kids using that. Plus our couch is a good 10-12 feet from where the Switch is.
