Congratulations!
Switch is an awesome device.
Odyssey is a mind-blowingly wonderful game for all ages—Production values and imagination through the roof, and my pick for best Mario game (*spoiler* early in the game, you can become a T-Rex).
Deluxe is a decent update of classic Mario gameplay, which—though simpler and more straightforward, is often more difficult than the open-ended exploration of games like Odyssey.
On that note, the limited-release Super Mario 3D AllStars is a good deal, bundling Mario 64, Sunshine and Galaxy. It’s recently discontinued, but you might still find it at Walmart, Best Buy, etc. as Nintendo manufactured a *lot* of copies.
Mariokart 8 Deluxe is one of the most fun, super-headliner E-Ticket games in human history, so you’ve made a great decision there!
Other fantastic Nintendo-developed Switch games for all ages: Super Smash Bros. Ultimate, Legend of Zelda Breath of the Wild, Animal Crossing and ARMS (fighters with slinky spring arms—‘nuff said
).
The new Mario Golf game is excellent; can be played serious or silly/chaotic. A bit light on content for the price, but they’ll be beefing it up this year with free DLC.
I could go on and on...
