If I buy something, decide I don’t want it anymore, I can refund it within 2 hours of playtime or 24 hours of purchase (I might have the exact numbers wrong, but whatever). I’ve only ever used this a couple of times, but this is a reasonable expectation if you think of a video game as a product that you purchase much like any other product. I’ve never had problems with refunds, ever.
One time I bought a game on nintendo switch, and discovered that I couldn’t play it because it required joycons and I didn’t have any of those. I attempted to refund the game, but nintendo won’t let you refund a game if you’ve downloaded it.
I still buy games on steam. My switch though, I gave that away.
