Well, this is what will cause the death of brick-and-mortar dedicated game stores. The inability to adapt to these times.
To be fair, I dont think this effects either the gameware or xbox that much. Since Xbox is non-existant in mainland europe anyways. Wouldnt be surprised if other retailers in the area do this too.
Now, it would be HUGE if a US/UK/Canada/Australia/etc chain tried to pull this off, which would be very unlikely.
Gamestop is already partnered with microsoft and already is selling one-month game pass cards, and are adding 6-month cards soon, so I doubt the two are on bad terms at the moment.
Bet with Intrinsic:
The Switch will outsell 3DS (based on VGchartz numbers), according to me, while Intrinsic thinks the opposite will hold true. One month avatar control for the loser's avatar.
