Can't believe I haven't checked in here recently.
I actually got Mario Odyssey a couple days before it officially released (Offer Up fell-off-the-back-of-a-truck Special, I believe.) Spent 2 full evenings and a full day playing through it (getting 500+ moons, for those in the know) - while I'm old an jaded now, I feel like it's honestly got most of the magic of Mario 64 and far more charm. I don't play many games these days, but I feel like it's a serious contender for the best game I've ever played.
I felt the same way about BotW, too. I genuinely feel like we're entering a golden age of Nintendo. In my mind, that's two of the best entries in two of their best series, and we're slated to get more cool stuff soon - the first console Pokemon RPG is heavily rumored. a Fire Emblem is slated for release. And new Kirby and Yoshi games both look to capture the best of their respective series.
