I've gotten Emberward recently. Roguelike Tower Defense where you get random tetris blocks to build your maze from. It's really solid TD gameplay and the mazebuilding is pretty interesting with a variety of levels that require a bit different strategy.
Difficulty is a bit on the lower end, but you can choose between 3 difficulties and I've mostly played on Normal. Heroic difficulty seemed pretty tough
Downward compatibility to play Switch 1 games.
Zelda Oracle of Seasons/Ages remade in the style of the Link's Awakening remake with both coming together in a bundle for a fair ish price.
Some older Gen 1-3 pokemon remake with some replayability feature like higher difficulty mode, nuzlocke mode, randomizer, etc.
Somehow there isn't any particular new game I can think of that I would really want...
