So, I can see it like this
>Start on the capital (central region)
>To travel, you use boats and trains (till u get surf and fly)
>Enemy team is Just Criminals
>>Unless you want to make it more "Chilean", in wich case you got more options for "evil" teams, like a team centered around one of the native communities (trying to reclaim land), a team centered around football (tho we sorta had that already) or a magma/aqua sorta team rivalry (team that wants more industrialization vs. team that wants to protect the nature)
>First Gym is either a poison type or a normal type
>Instead of rat based mons, you get Cat and Dog base mons at first, with the usual bird (Chile has a lot of street dogs and cats)
>starters should be: Pudu based grass type, turns into Grass/Ground type in his final stage (while I know Virizion and Deerling exists, its kinda hard to think at this point of new starters)
Fire based Bird (Condor) - Turns into Flying/Dark type at his final form
Fish water mon, just that honestly, having such a long coast line, not having a lot of water types would be dumb
>North would be mostly rock/ground types
>south would be different, more grass,ice,psychic,ghost types, with lots of different water types
>Nossepass at easter island of course
>legendary(s) is/are giant snek (sea snakes)
