Microsoft has confirmed recommended retail pricing for Xbox One games in the UK. The manufacturer's online store currently has Ryse, Dead Rising 3, Forza Motorsport 5 and Kinect Sport Rivals down at £49.99 - more or less in line with the RRP for Xbox 360 titles.
If £50 sounds a bit steep, that's probably because you're used to buying games at a retailer discount - Xbox One games will undergo the same whittling-down process once they're in the hands of those who sell them. Eventually, anyway. This being the start of a console generation, Amazon, Shopto and so forth may wish to price games nearer the RRP for the moment. First-party Xbox One games carry an initial pricepoint of $59.99 in the US.
