Some recent games I've enjoyed (fair warning if you buy digital games some of these RPGs are pretty huge GB-wise)
Xenoblade 2 - Very cool title. The combat is pretty cool, and the world building in top-notch. Heavy emphasis on exploration. There's a ton of side areas, hard to reach treasure, side quests, Merc missions, and developing the main Titan communities. The Legendary blade quests really help flesh out otherwise bland side characters, and give them more personality. Rex is a little bit annoying due to being a kid, but is more than balanced out by Tora, Nia, and the other characters in your traveling band being very enjoyable. The backstory between Mythra and the other blades from the past was interweaved into the story well.
Final Fantasy X / Final Fantasy X-2 - haven't played either of these before, although I have dabbled in some other FF games in the past. Found these to be very enjoyable. Titus took a while to grow on me, but about halfway through he became a pretty strong lead character. The sphere grid system is a cool level up system, especially with some of the more limited spheres. The only real complaint I have is that FFX doesn't let you backtrack until the very end of the game. FFX2 is noticeably lighter in tone, and it's nice to see a different version of Spira. FFX2 also uses a different combat system making it a better change of pace in a lot of respects, even with a mostly returning cast.
Dragon Quest XI - My favorite switch game so far, I think. My first playthough ran over 130 hours, and that's not even 100%ing it - excited to start another playthrough with Draconian rules on. There’s an overwhelming amount on content. It's a classic RPG in its structure, but every single aspect is so fleshed out. The characters do fall into classes to a degree, ie the Luminary as a paladin, Eric as a Thief, Serena and Veronica as mages, etc, however the game does an excellent job fleshing them out and developing their characters, especially in Act II. The games UI is top notch, it’s beautifully animated, and the in-game bestiary and item listing are incredibly robust. The forging system is really novel as well. The areas are all very distinctive with one or two exceptions, and it didn't feel laborious trekking through them again during each act. The endgame was pretty challenging and some areas are really difficult even at level 99 with great equipment (especially if you avoid cheesing with Eric).
