Top 3: -Super Mario Odyssey: Bought the Switch just for this game. Glad that I did, as it might be (imo) the best Mario game that ever existed, so far.
-Persona 5: Had an issue with a dungeon (fuck Dungeon 5 and how long it is), but overall, it's oozes with style at every corner. And I love it.
-Tekken 7: Prob the only Tekken that actually got me serious into playing and learning what the mechanics have to offer. Combos felt fun (but super strict) to do along with how satisfying some of the fights can be when you win with an inch of your life left (with the slo-mo elevating that feel of "oh god, am I going to win!?"). Story could have been better, but the ending fight, not Shin Akuma's, was worth it all around.
Honorable mentions: -Breath of the Wild: Just got started playing this game. It's fun, but gets somewhat tedious at times. Never like the implementation of motion controls in this game.
-Sonic Mania: Very beautiful game all around. Too bad that I didn't finish it.
-Cuphead: Animation and artstyle are so damn good. Can't finish it tho cause it loves to kick my ass.
-Yakuza 0: Good introduction to the Yakuza series. Didn't think it had enough going for GOTY, especially with maybe some pacing issues and maybe some glitches here n there.
