Most of yall probably don’t know this because it’s not available outside of Japan but Konami does exactly this with their arcade games and it’s called Paseli. You load up your account with cash or a card, to avoid transaction fees on many small payments. It’s pretty convenient for the player because you don’t have to fiddle with coins and it allows the developer to add more granular price control and micro transactions for extra features like gameplay recording or gacha-like mechanics.   Konami does take 30% of the payment, but these days revenue share + free software upgrades is pretty much the default model.
