You really should play Sunset Overdrive
One of my fave Xbox One exclusives, and one of my fave new* games so far of the new generation.
*(excluding the endless remakes/remasters etc.).
Yup, still only buying digital downloads.
I almost always buy my Xbox credit from CDKeys.com.
I did try an eBay seller once, but it turned into a massive hassle so I've avoided that route since then.
