It's a significant upgrade in all areas, be it geometry, textures, overall image clarity, the lighting, AA, AF.
There are significant changes in all areas of the visuals for sure.

I think the remaster is also 60FPS too.
The difference should be on this level, great to see such an awesome job being made of this.

I have the vita game, but something about it felt a little off too me, so I could never really get into playing it through, but the vast improvements here make me want to get this.

Looks way cleaner and you can make out a lot more detail. Same picture, just presented much better and more accurately to the art. This is a similar comparison to, for example, the same movie on DVD vs Blu-Ray. I mean, it's the same thing, but damn does it just look a lot better and easier to make out the detail on the upgraded version! I've already played this on Vita, but when I can get it for about 20 bucks on PS4, I'll play it again in its new & improved format.

it has been free with PS+ for over a year with Uncharted.
I have to admit, this remaster is so tempting. I hope they keep the gyroscope gameplay with the DS4 and not only the R stick

30 is way too low over the entire history of Playstation, I just wouldn't be able to narrow it down that much, I would pick 100 at least.

Yeah...really odd list. I get that it is personal preference and I love most of the games listed, but my list would definitely be different. I agree though, it would be incredibly difficult to come up with just 30.

I only picked first-party titles. Otherwise, I agree!

EDIT: Except for Days Gone, I don't get the love for it but you do you!

Tried them, not my cup of tea.

Beat them both, awesome games!
