As already described above, I have a question about the prepaid cards.
I'm going to buy Xbox Game Pass for PC, will I need to buy an Xbox prepaid card or a Microsoft prepaid card?
I think there are even gamepass cards
Yes, but there's an offer for 1 euro for the first month and this offer can't be used with the gamepass cards
Microsoft and Xbox credit, that's one and the same credit.
Xbox and Microsoft are only separated because Xbox is Microsoft's gaming division.
