Metal Gear Solid creator Hideo Kojima has commented on the Metal Gear Solid V: Ground Zeroes comparison of current to next-gen.
"I published comparison images of consoles since I get so many questions. Once I said the contents & controls can be equally amused by player as we carefully adjusted, people say ‘then next-gen is meaningless’. Well, I want people to play next-gen if they were able to buy, and for those who couldn’t, play current-gen version as [Ground Zeroes] is indeed multiplatform.
"Next-gen looks better because of its hi-specs, but what I want you to feel is the point [that] the photo-realistic image we pursue in Fox Engine made even the current-gen look as good as next-gen. Nonsense to compare simply b/w [Metal Gear Solid 4] & [Ground Zeroes] since [Ground Zeroes] is an open world game though."
