Personal recommendation: Mr. Driller Drill Land is an excellent, underrated puzzle game that is less than $5 right now.
Don’t buy Civilization 6 for Switch. I have it. It’s a great game, but at a certain point of complexity (large civilizations with many units), the game will just run out of memory and crash repeatedly at the same point. This has happened to me multiple times, and they’ve never fixed it. I wasn’t even playing on very large maps.
