Metal Gear Solid V: Ground Zeros length concerns hit the net

MGS: Prologue reported to be short

Metal Gear Solid V: Ground Zeroes is approaching its march 31st release date and its PR machine is building up and GameInformer has been spending a lot of time with the Prologue chapter for Metal Gear Solid V: The Phantom Pain (which is expected to land in end of 2014)  and recently some concerns arose when it was discovered they complete the main story missions in under 2 hours.

Hideo Kojima himself has come forward on his twitter account and had this to say

It should also be noted that Ground Zeros and Phantom Pain are open world games and faffing (messing) about will take up time.

SIDE NOTE amazon currently have MGSV: Ground Zeroes for Xbox One for £28 which is pretty cheap for a big name title on next gen

UPDATE: PS4 version also £28
