Game I played (and still currently play): Tactical Nexus, imagine Tower of the Sorcerer but with all kinds of new things to do and metaprogression in each tower (at the end of a tower you get a medal which you can use to open special "medal doors" in the same or different towers).
Although I don't really like the way the DLC is priced ($15-25 per additional chapter to a grand total of $100 for all DLC), you can play the game a lot with just the first 2 free chapters.
Game I want to play (it doesn't have to be an existing game, right?): Super Mario Maker 3D. Like, even the Switch is powerful enough to give players a simplified 3D game engine like Game Builder Garage, so why not just extend that concept to Mario Maker? It would be so amazing to finally get more Mario Galaxy and the like.
Game I'll never play: League of Legends, like everything about the game is the opposite to games I play: super long game sessions (with penalties for disconnecting), it's a major competitive sweatfest like Splatoon Ranked, the premium currency cannot be obtained without paying, and it's owned by Tencent.
