GTA 5 would have topped UK download and retail chart ahead of Mortal Kombat X

Following its long-awaited release on PC, Grand Theft Auto 5 would have been the UK's top selling game if official data included digital downloads as well as retail, reports MCV.

Its sources claim that GTA 5 would have sold six times more than the figure released by GfK Chart-Track if downloads had been included. The official data on boxed game releases has awarded the number one spot to Mortal Kombat X, but given only a small percentage of PC business is conducted on shop shelves, the data is misrepresentative of business reality.

MCV is in the process of putting together its own chart data which includes digital downloads, saying that "several publishers" have already signed up in the face of the increasingly archaic GfK Chart-Track data.

Despite GTA 5 having sold more this week, Mortal Kombat X has still been a big success for Warner Bros Interactive and developer NetherRealm Studios. It is the second biggest game release of the year so far, behind Battlefield Hardline and the biggest ever UK launch for the famed fighting series.

GTA 5 placed second in GfK Chart-Track's top 10, which did included boxed PC releases.
