Kojima adressed a question on his Twitter he gets asked a lot: which version of Metal Gear Solid V: Ground Zeroes to buy. Here is what he said.
I’ve been asked which ver u should buy. The feel of play & impression’s similar as it’s been made multiplatform/multigen” this time.
Sense of realism & graphics looks much better in next gen. So I’d say currentgen for those who can’t buy next gen just yet & upgrade later.
FYI, the world ranking of mission result/trial grade in “GZ” differs to each platform.
The feel of play/difficulty levels are the same as we consider slight difference parts found in each hardware, controls or frame rate.
So according to Kojima, each version has been tailored to the specific hardware. Also, interesting to know the rankings are different for each platform.
