Following reports that prices for digital copies of Ryse: Son of Rome, Forza Motorsport 5 and the standard version of Dead Rising 3 had increased by £5, a Microsoft UK representative explained the change to GameSpot this week.
"Digital content pricing is subject to change and we may occasionally offer various deals or promotions," the spokesperson said. "Yes, pricing for select digital content in some markets has changed since launch."
With the changes in price, all of Microsoft's first-party, retail-sized games that are now available for download on the Xbox One are currently £49.99.
