<i>iOS or Android or whatever else OS</i><p>You just answered your own question.<p>Remember the screen paradigm. In the 80s, Nintendo made it possible for developers to make games that worked on Zenith TVs, Magnavox TVs and RCA TVs, but they only had to develop it once, for the NES.<p>The Playstation VM means the developer only needs to make the game once, and Sony is doing the work to make the VM work on iOS phone, iOS tablet, Android phone, Android tablet, Windows, Windows phone, Visio TVs, Samsung TVs, etc etc etc.<p>Plus it can&#x27;t be understated that there still needs to be a controller. Touch screens just don&#x27;t offer the immersion that controllers do.
