I still have my New 3DS, I bought it 5 years ago. It actually my second 3DS, the first one was sold so I could have bought a VITA
I also have some games need to finished like FE Echoes, Luigi Mansion, Persona Q, Mario, Pokemon,.... so much games in backlog but too little time to play.
I loved all my finished games on 3DS. Stella Glow, Fire Emblem Awakening, Pokemon X, Azure Gunvolt, Radiant Historia,...
Stella Glow is my GOAT on 3DS. I love it. And FE Awakening too, one of the best SRPG. Pokemon X may not the best game, but it's only 3D Pokemon game I finished, until I got a Switch Lite and finished BD (Gen 4 remake). Azure Gunvolt is so much fun and fast-paced. Radiant Historia is great JRPG too, with time travel system. And other games that I am not mentioned, all of them are very unique, fun and easy to pick up, learn and play.
I had played DS, VITA and also Switch Lite, all of them are handheld, but 3DS for me is still the best, because I have many time for it because of my time in college.
Also, I wish every handheld has time-played detail record feature like Activity Log on 3DS.
