Some of these were already mentioned but nevertheless, amazing music is present in many great games!
Final Fantasy IX, Hollow Knight, Final Fantasy XIV, Witcher 3, Outer Wilds, The Talos Principle, Disco Elysium..
But my absolute favourite soundtrack from a game is one that I love even more than the game itself (which is absolutely fantastic, too!).
NieR: Automata - the music is just otherworldly. It fits the game but even when I am just listening to the soundtrack by itself it just makes me feel things. An absolute masterpiece.
Yup, thinking back on it I think you nailed it. Especially that part about being more "free to just enjoy things". I mean it usually almost goes without saying but I wish I could at least somehow do it - enjoy things I want to enjoy (not just games) without having any thoughts in the back of the back of my mind which are bogging me down. I am quite sure you are correct on this part. And the first part is quite true as well, I have x amount of games on my two PlayStations, y amount of games on GOG and z amount of games on Steam. Similar to your experience, back when I was playing FF9 I remember I only had 3-4 games in total, too. FF9, Metal Gear Solid, Gran Turismo and Crash 2. So you are also quite right on this point. Right now even when I am playing a game, I am not fully concentrated on it because of that "mental tax of life" + I am always thinking about my catalogue of games I wanna play and even of games I should get and try, etc. So yes, perhaps I need to learn to relax :) Three games are coming this year which I am extra excited about - Baldur's Gate 3, Hollow Knight 2 (hopefully!) and Hades 2. I will do my best to tackle just one at the time without any of these pressures and we'll see how it goes. And even if I cannot really devote as much time to playing as I could back then, I will just take longer. Who says I need to finish a game in any amount of time? Thanks for "tiny therapy", Crotaro! :) Maybe I'll update you here later this year about this. Hopefully, my mind won't be as weak as it was when I played Sekiro and Hollow Knight - after first trouble of getting something, I've tried once or twice to get it and then - immediately ran to internet. I will try to avoid this with these 3 games (and hopefully others).
P.S. I am now replaying FF9 on emulator and I remembered so many things even after 20 years :) so "technically" it's not this "gameplay challenge" it was back then but still having an amazing time with it because now I am picking up things in story and dialogue that went over my 12 year old head.
