Let's discuss why Hoenn is objectively the best designed region!
>hosts the longest and most complicated routes in the series (including the biggest Safari Zone)
>greatly interconnected, always providing useful and interesting shortcuts when you need them for backtracking or are just exploring
>dungeons with unique themes and mechanics like the Trick House, Abandoned Ship, and Shoal Cave, as opposed to just generic caves which is most of what certain other regions offer
>unique and memorable towns like Fortree, Pacifidlog, and Sootopolis
>optional nooks, crannies and locations everywhere like the desert, New Mauville, the aforementioned dungeons, and the vast majority of the sea
They really knocked it out of the park with Hoenn, eh? Hard to believe that Ohmori worked on RSE as a map designer when he later went on to direct the shittiest games in the series with the worst region level design ever.
