We neither want to add friction for players nor do we want to benefit from accidental purchases or players regretting a purchase.
Our initial solution for this was to add a refund token system.
As an ongoing iteration, we are going to introduce an “undo” button to the store page that allows you to easily refund without using up a token within a 5 minute time window, assuming you haven’t started a match since purchase.
PlayStation 4 in Japan is a bit of special case due to X / O button meaning being swapped by default and there also being options to reverse the meanings of the buttons.
