I replay it every year to see if it still holds up, and it really does. It is not without flaws, but the package as a whole is really quite something. It saddens me that we will never see its like again.
Not saying your opinion is wrong, but I find games like that ultimately too lacking in depth to be the answer. Yes the core mechanics are solid as rock, and the game is universal in that the rules are clear and easily understood by all players, but that is because there is little to understand beyond the most basic concept. It's the same reason I would consider chess an objectively better game than naughts and crosses. Tetris does what it does flawlessly, but it doesn't do much and that is why it can.
I feel like we have this thread come up at least annually.
It comes down to how we define perfection, and for art, games in this case, I don't think it's about being all things to all people - that's "Tetris" perfect - but how well a work executes on what it sets out to do.
Bloodborne is absolutely on that list for me. I'd consider Dark Souls my favorite game of all time, but you have meet the game halfway too often over a very long campaign. Bloodborne is just pitch perfect throuought.
I think Mario Odyssey is an example of a "perfect Mario game", where is does manage to be all things for all people, but it does make me long for other titles at moments like Sunshine, Galaxy, and 3D World. The feeling will pass by the next moon.
Tl;dr : I think perfection is relative to the title first (perfectly executed idea) ,the player experience second (perfect for me), and "perfect for everyone" is a compromise.
Also, this has been said a lot before but, in terms of the experience Ocarina of Time. It's not perfect technically, but I believe part of real perfection is having a few flaws and rare lows so you can appreciate the good parts. If the game is 100 % linearly good I wouldn't necessarily consider it perfect. To me at least. If you take everything for granted you're not truly enjoying it, you might mistakenly think you are, but I don't think so.
