You're saying that 1080p doesn't look substantially better than 720p (among other differences that those games came with in favor of PS4)? I sure hope not. And, why ignore Metal Gear? For you to say the difference in each system's power is marginal, you'd have to provide something that proves this (as I asked him).

Currently, you have nothing to work with. 

Ghosts on PS4 looked better but not by much.  You just look at numbers 720p and 1080p and think think game looked twice as good on PS4...That is ignorance.  

Metal Gear is ignored because we know who the developer is and know they didn't give a damn about the XBO version. 

The color balance and crushed blacks were horrible in the X1 version, not to mention all the jaggies that were pretty conspicuous.

I'd advise looking up the word "ignorance". You've misued it here. If res was the only difference within the game, which is already big, you might have a point. But it wasn't, and that was far outside of my point. Currently, you are the second person to quote me without providing solid answers to my questions.

I'm starting to think that there isn't one. 

My opinion is that they both looked like crap and both had framerate problems.  Comparing that abysmal game to anything is a waste of time. 

Wouldn't be more funny if x1 cod outsell ps4 cod? because um.. you know... sell gap difference between the two? O_o

Ah, but your opinion about the game itself is irrelevant when talking about technical, factual, differences. 

Um, a 50% difference in resolution, alone, isn't substantial? Got it.

Good day, sir. 

Same number of pixels on the screen.  I mean just look up uncompressed images of the two to educate yourself.  Upscaled is blurrier when you get up close to the detail, but when you are playing at 60fps, you don't notice this unless you stop, stare and anaylyze.   It is not some massive difference like you think it is.
