Late to the party, but I enjoyed the Direct quite a bit. Animal Crossing is a big deal for me, as well as all those classic FF game ports. The new Game Freak game looks cute, though considering how early in development it is, hard to say whether it will be fun. Interesting ports like Civ VI and Cities Skylines, Civ being a series I always thought would be good for Switch (though I wonder how long turns will take late-game) and the other being a game I'm legit surprised can even run on the Switch. Not a Luigi's Mansion fan but a new one will certainly make those fans happy. As for NSMBU, I would have preferred a Mario Maker port (though the fact that they've avoided it until now makes me wonder if a new one is coming), but I guess NSMBU is a good game, so it's worth giving it a 2nd chance on Switch.
Also, happy to see barely any Smash, really tired of all the overexposure (Unpopular opinion, I know)
