Gaming

On the switch you have Skyrim (but I'm assuming you've played that)

But also there's a couple games that could be worth looking into. I have no idea how well they play on the switch or if they would even be your cup of tea, but there's Dragons Dogma(the first one) and also Outward. Again no idea how they play on switch but they're both open world rpg type games.

If you're up for something that is specifically all about exploring, you could try Outer wilds on the switch(this does not have combat FYI) but you get to explore a solar system and unravel a mystery.

Might I recommend Romancing SaGa 3 and SaGa Scarlet Grace Ambitions? Both of these games involve non-linear, open world explorations. As for combat, they are turn-based, so I'm not sure if that's what you would consider a "good" combat system. Also, unlike traditional RPGs, which use a point-based system to level up and gain new skills, SaGa games involve a "Spark" system, where new techniques are learned randomly or through use of an existing technique during battles.
