I stated the new Final Fantasy Resonance. So far, it's solid. No regrets choosing Switch 2 over PC. Performance is smooth. Recommended for any FF fans.
I've also been playing Echo Weaver, which is a metroidvania sidescroller with time-loop mechanics, where the main thing you gain between loops is just knowledge. Honestly, this isn't my genre of choice — I can't remember the last metroidvania game I played for any length of time — but I was intrigued by the time loop aspect. So far so good, but I'm only just as the first boss so time will tell if I stick it out. Performance in Switch 2 is not totally smooth unfortunately. FPS drops fairly frequently. It's definitely playable but I'm disappointed that what seems like a modest 2D game has any performance issues whatsoever.
Since I'm not really into the genre I'm not sure how it compares to others but I'm having a good time.
