Your argument is irrational and makes no sense, no offense. As a game developer you should understand the idea of taking an existing game, made with hardware limitations, and porting it to a new and better platform.
Reagrding the sushi stuff, I won't argue with you. It is a matter of taste, and gentlemen won't argue about taste
However, there lies a cold, technical problem:
You mention this: "porting it to a new and better platform".
I'd alter tho this: "porting it to a
different platform".
Big difference.
The original game has been designed to a locked 30 fps - and here comes a very not-so-popular statement:
FPS is not just about making the graphics smoother, but, more importantly, synchronizing game systems together.
If I make a game for, say, 30 fps, I have an exact time budget for everything: graphics update, physics, AI, game logic, input, network, whatever.
Now comes the fun stuff: me and my QA team will balance and tweak the game systems till it "feels good" -- but the "feel good" effect is valid for 30 fps only!
The whole structure will break apart if I raise the fps to 60 or more, and we need to re-balance the system again, else e.g. the input might feel "floaty", AI/game update will be out of sync with the physics, etc.
These issues are not deal-breaking bugs, mind you, but annoying glitches that gamers might feel "odd", "shit", "uneven", "not right", "broken", etc.
In layman's terms: that's why it is so hard to make a game run on "whatever" fps. (And that's why we adore John Carmack, who first pointed out this very problem. His engines were all about optimal balancing and not about graphical pyrotechnics.)
And that is why most game developers stick to one very specific target when making a game. Easier to balance, easier to deliver that surgically precise experience the designer wants.
Also, regarding your argument about the Last of Us remake:
You are partially right. Yes, on PS4 the framerate is better, the controls are a bit tighter, the overall gameplay might be improved.
BUT. The amazing somewhat low-res graphics was completely botched, because many textures and meshes are sub-optimal on full HD, disgracing the art team's 5+ years of hard work.
So I am still not convinced whether this version is the ultimate. (I consider the game as "incomplete", hence there is no good version)
FYI, the only remaster I really like somewhat is the Shadow of Colossus remake on PS4 -- the original was pretty much unplayable on PS2, but again, the "HD"-artwork was still way worse than the original's amazing experience on a decent low-res CRT tv set. (Again, another "incomplete" game here)
Gamers, please note:
All remasters and conversions are trade-offs. Always, and no exception.
But, that's enough about this. Enjoy any game on any platform you fancy, and that's it.
