>>44288321>Don't know how that can be corrected while also linking up the world or maintaining some regular routesI think the easiest way would be to make the Wild Area the central hub of the game. Make Wild Area's train station the Grand Central Station full of a ton of useful places like a Pokemon Center, BP Shop, other Watt Traders, Shop that sells more things than the regular Shop, Move Tutor or 2 hanging around etc.
And maybe have all the routes branch off from that Central Hub, so that you end up revisiting it at regular intervals regularly unlocking new additions to it for you to make use of.
