Every single PS4 game will be playable via Remote Play on PlayStation Vita.
That's because, unlike on PS3 when the functionality needed to be specifically coded in, PlayStation 4 will allow Vita streaming on a system level, Engadget reports.
Sony Worldwide Studios head Shuhei Yoshida told the site: "On PlayStation 4 it just happens. You just make a PS4 game, it supports Remote Play.
"The single biggest issue, why there are not many PlayStation 3 games that support Remote Play, was that it was optional – the system didn't do much. The game has to set aside some memory or CPU to be able to do that, and usually, memory is the most precious resource that [development] teams fight amongst each other for. So when it comes down to the priorities, these are features that are very easy to drop.
"Please make sure that when you play your games on Vita, the control is good. That's the minimum thing we're asking them to do."
Obviously there technically are bound to be some exceptions – with the PlayStation Eye-requiring Just Dance given as an example.
