I have problems with nostalgia all the time
Ive been playing since Blue came out, got a Gameboy and that game as my first game. Absolutely loved it, and Ive probably played close to 10,000 hours of Blue. I know back in its day I would go weeks of playing it haha. I still play it to this day.
I have never played competitively, so exact stats and everything were never something I needed to know or care about, yet I could probably tell you everything about Blue and its pokemon. I could tell you where every hidden item (or not hidden really) can be found, I know what pokemon every trainer will use, I know where every area is on the map like the back of my hand, and I know who will be standing where, etc etc. I could probably tell you what level 80% of the pokemon learn what moves at haha
When I played x for the first time a month ago, I did actually talk to every single person I came across, and I hunted each set of grass for a good half hour just to make sure I could find most of the wilds, even rare encounters. I actively tried to catch them all.
But you know what? Even now, I hardly cared. I mean, it was fun and all, but when I played Blue, I got into it. The story wasnt as deep or anything, but I cared way more. On X, I cant name a single city or town (maybe camphrier town or something like that? only because its the pokemon center nearest battle chateau).
I just dont care. Same goes for everything after gold/silver. After that point, you get so good at the games by nature, or if not amazing at them, at least you become accustomed to them. Its like you dont need to focus so much, you dont need to get so into the game to play them. You no longer need to care what this or thats pokemon name is or where its found, because you know it blows as a fighter, so whats the point. Even the ones you use, you might not care about the details any further than knowing this one is a special attack sweeper, this one has super high HP, this guys an HM slave.
I went from going through games and becoming part of the game, making it my world, to rushing through games to win. Then when you play, youre just like well that wasnt as good, that wasnt as rich as it was before. That is only because you didnt let yourself become part of the world you were playing in, and quite frankly, it is very hard to do.
The 30th time you watch Lord of the Rings, you dont care about them running across mountains for half an hour, you dont want to hear the legolas gimili jokes, you know them all. Maybe you only pay attention during the big battle scenes. And then you wonder why it didnt feel as good as the first time - its because you arent watching it, hanging on every word.
