I always loved how Gold Silver & Crystal felt like pseudo life-simulators
That statement might seem a bit weird, but like. The real time clock, daily events, and being able to phone trainers you fought really makes the world a lot more cozy. It feels... alive? Sorta the same vibe I get from old Animal Crossing games, but if it was on a Gameboy, which is just so interesting and intriguing to me, I love it!
First off, they introduced the berry trees that respawn daily, immediately giving you a reason to get on every day. Even if all the progress you make in a day is getting to Mr. Pokemon's house, you will have found at least 3 trees you can harvest for useful berries, which tapers off into you picking select beneficial berries every day that you play.
Getting to see different Pokemon depending on the time of day is a really cool concept, too! ...I just wish they had a few more nocturnal Pokemon, I feel like Hoothoot/Noctowl is found on pretty much every route at night lol
Then there's the events. Smaller things like the Lottery, Lapras on Fridays, Bug Catching Contest, shops in the Goldenrod Underground, Buenas Password, and even the Rival Rematch.
Tons of things for you to look forward to through the week that can benefit you in a number of ways! I feel like I'm forgetting a few daily & weekly events, but there are a TON for a GBC game. Sometimes I pour a majority of my play time doing these instead of doing the main story lol.
And theres also the Pokegear. I know its pretty divisive among fans, usually seem as an annoyance that causes you to get seemingly random & useless phone calls that generally waste your time, but I find getting to talk to trainers in the world makes it seem more cozy. They tell you all about their exploits, what they've done, how their Pokemon are. I generally find it cute, seeing their teams grow with every rematch is also really neat, it makes the world feel like people are growing alongside with the player.
I havent even mentioned the NPCs who call to give you free items, or warn you about swarms! People may find them annoying, but I always do my best to fill out my Pokegear with trainers who I think are cool.
I'm especially fond of juggler Irwin, he likes to call you after each gym badge to congratulate you on your victories and is generally pretty goofy in his calls.
It's all pretty basic, but it means a lot to me. Its one of the main reasons I like coming back to GSC so much, the world never fails to captivate me. It really feels like the world is alive, and helps make me feel more immersed when I'm spending time in Johto. It's nice. :) Does anyone else feel this way??
I also love that DP/Ptt pretty much took GSCs daily events, and cranked it up to 11. I spend way too much time in my Platinum replays just focusing on the daily Pokemon Center fights, the Lakeside Resort fights, magazine sidequest, Sunnyshore City Bazzar, Mass Outbreaks, the Drifloon on Fridays, the lotto, etc. I mainly just wanted to gush about GSC in this post, but I figured bringing up DP/Ptts daily events was relevant bc theres no way they werent inspired by GSC lol
