I’m including anything only available on other Nintendo systems as exclusive for this.
I’ve got a $50 eShop card I figure I should spend before gold points go away.
I have BotW. It was alright, but it didn’t excite me enough to get TotK unless it’s on a deep discount.
I’ve also already got Mario Odyssey and Metroid Prime Remastered. I have a handful of other games but they’re not Switch exclusive afaik.
I’m mostly using my Steam deck for handheld these days, so I’d rather not get anything non-exclusive on the Switch right now.
I’d say Breath of the Wild/Tears of the Kingdom, but seems like that’s not what you’re looking for.
The Paper Mario: TTYD remake is very good. Or Animal Crossing, if you’re looking for something relaxing.
For party games, Mario Kart 8 is always fun. And of course Smash Bros Ultimate if you like that series.
+1 to Animal Crossing. Love the aesthetic of cozy games but sometimes a lack of a solid goal, for lack of a better word (casual games are games, not being judgy about that, they are just not to my personal preference) casual-ness/lack of complexity, or not-the-best gameplay drives me away. I enjoyed Animal Crossing a lot.
Mario Party Jamboree also pretty cool for party game
I agree with these recommendations. All terrific choices!
