I 
know y'all ain't talking smack about the GOAT region, Sinnoh. 
In all seriousness though, and that's a lot coming from me, Platinum is starting to show some wrinkles.
Not in the "omg, what a hag" way, but right now, in my opinion, it leans closer to Ocarina of Time.
I'll explain. Ocarina of Time needs no introduction, it's a generational game in every sense of the word, and it is recognized by many, including awards in an era when they actually evaluated games, as the game of the century.
More accurately, the game of last century.
If one were to play OoT in 2025, they would certainly recognize it as a masterpiece, but it just feels a bit... dated at this point. Mind you, I'm not talking about the graphics. For example, the warp points are 
extremely inconvenient.
Similarly, the best way to play Platinum nowadays is on an emulator so you can have easier access to QoL patches, and PkHex because IVs suck.
Granted, those could've been fixed by a remake, but... 
Basically, what I'm saying is that as great as Platinum is, by now, it's more of a gold standard than an undisputed #1. Which is even more impressive tbh, there aren't a lot of games that can stand the test of time like this.
Platinum, and Emerald while I'm at it, have a LOT of lessons to teach to the newer games. When it comes to things like map design, they're still undefeated in this franchise.
Hell, Platinum still has the most iconic in-game team of all time, and unlike the Kanto games, it's not because of a lack of options early-game. But in terms of QoL, it has long been surpassed.
As for the last pages before this post... Man, I can't believe y'all still talking about Dexit. 
But that's a topic for another post.
