Many digital store fronts add good with refunds. One reason is that payment gateways sometimes charge $5-20 for a dispute. As a result it’s cheaper to refund a customer than trigger a dispute that will cost way more than what the digital good is worth.
Nintendo and Sony don’t! They warn you once you download the game you cannot get a refund. Steam and Xbox are definitely the exception and show how it should be done. I’m in two minds on whether to play Atomfall on PS5 or Steam Deck lol.
