I’m sure this was expected (not like I was hinting at it in my last one), so let’s begin. The GBA was a different beast to the Game Boy Color, and Game Freak used that upgraded hardware to build a fundamentally different world to the ones before. When you look at the specs, the change to 32-bit meant the developers finally had the power to make environments with actual verticality, and complex weather systems. Gen 1 and 2 were built on flat, single-layer grids where the developers had to use visual tricks to fake any sense of elevation (which was incredible), but Gen 3 introduced a multi-tiered world where you could walk under bridges, and see your character’s reflection fully rendered in puddles on the ground. It allowed Game Freak to add a cohesive, interconnected ecosystem to it’s already living worlds.
The layout of Hoenn is a recreation of Japan’s Kyushu island, and the development team went to insane lengths to adapt the real-world topography into their game. Junichi Masuda and the team took the actual map of Kyushu and rotated it ninety degrees counterclockwise. I remember when people used to spread rumors on old forums convinced that the developers rotated the map because of cartridge memory limitations or because they wanted to hide the real-world inspiration from western players, when no, the reality is that it’s strictly tied to game design and hardware formatting. Masuda rotated the island to fit the layout of the Game Boy Advance’s horizontal screen and to balance the ratio of landmass to the massive ocean routes they planned to add. They mapped the real-world Mount Aso directly into the game as Mount Chimney, and the famous hot springs of Beppu heavily dictated the look of Lavaridge Town. Instead of adding the time of day changes like Johto, they added specific, coordinate-based weather systems that altered the environment depending on exactly where you were on that map.
I’m bringing up this hyper-specific geographical permanence because my own real-world instability was really starting to take it’s toll on me during the years I spent playing these games. My family was dealing with severe housing instability, which meant we were constantly moving from place to place without any warning; and as you know I was also an undiagnosed autistic kid with ADHD, and my brain required a level of routine and order that my physical environment completely lacked. The chaotic, unpredictable nature of my daily life made the rigid but ever-changing structure of Hoenn incredibly important to my psychological well-being. I used the absolute predictability of the game's map to learn my geography because the rules of this digital environment never changed on me. The routes connecting Rustboro City to Verdanturf Town were hardcoded, and the specific spawn rates of the Pokémon within those routes operated on a reliable logic.
This meticulously designed game kinda functioned as my permanent residence and my actual roots. Game Freak’s obsession with spatial relations in Generation 3 forced me to thoroughly understand the terrain I was in. The map design requires you to backtrack and re-engage with previous areas using new HMs, which naturally builds a geographic familiarity with the region. I of course, memorized the exact step counts between towns and the specific layouts of the cave systems because having a predictable space to navigate gave me total comfort. I’m sure it’s also the reason for me being very good at mapping places out in my head nowadays too.
Hoenn also provided a highly structured framework that literally taught me how to socialize and find a community as I was starting to get older. The Secret Bases allowed me to claim a permanent place and decorate it however I wanted in a completely secure environment. I think people have forgotten that mixing records was a thing. Via the link cable, you could mix records with other people, and it caused their secret bases to permanently fill my save. Having the physical representations of other kids show up in my predictable world gave me a safe, low-stakes way to practice interacting with people. I learned how to build friendships by trading Pokémon and sharing these customized spaces within the safety of the game's strict parameters, and provided the exact anchors I needed to survive my childhood, and the brilliant architectural design of Hoenn is the direct reason I was able to find any genuine happiness during that time.
