Sony never said ever single PS4 game will be remote play compatible, Diablo 3 will not support PS Vita remote play for a pretty good reason, more details inside……….
Senior level designer Matthew Berger revealed that Diablo 3 on PS4 will not support remote play:
"Not really. Not for the moment,"Matthew did provide a reasonable explanation for the lack of remote play however, Diablo 3 is a very cluttered game and it will simply not work well on a smaller screen which has not been adapted:
"The Vita is an amazing piece of kit, but the screen is still smaller," he said. "And when you look at--and also it has its own aspect ratio--and when you look at Diablo III, there's a lot happening on-screen already. You get surrounded by your enemies, lots of effects flying off in every direction. The inventory can be pretty complicated to navigate sometimes when you have lots of items."Blizzard did not completely kill the possibility of Diablo 3 remote play though:
"So it would be a little bit more of stretch. It's kind of percolating in the back of our mind, but we don't really have any plans right now,"Let us know what you think of Diablo 3 on PS Vita in the comments below!
