Even if there's no content/graphical difference in a game (like Natural Doctrine) I still prefer to get it on the PS4 because of the system's interface bells & whistles - ability to capture video/screenshots, ease of switching to Netflix/Hulu/Amazon & watching something and then switching right back to where I paused the game, etc.
+ the better controller too, no?
for Pier Solar - w/ all things being equal between the PS3 & PS4, shouldn't the 'same' HD graphics still (theoretically) look better on the machine showing it @ more FPS?
I don't really know and/or understand shit about tech, comps, AV, etc but, I thought that was the *idea* or rule; isn't it?
