>>36158524Sinnoh was the peak of region design because from gen 1 to 4 the regions grew bigger and more complex with way more detail, but after gen 4 Masuda stepped in and decided to make a circle because Japanese kids got lost, and the series hasn't recovered since. Alola is such a fucking joke.
It all really ended after Sinnoh in terms of region design and scope. Instead of getting bigger and more complex like Hoenn did to Johto and Sinnoh did to Hoenn, the regions got more linear and cramped.
