No, cause that's an awful idea. You either fuck up the levelscaling trying to get everything wrapped in 100 levels or lower; you are forced to raise the levelcap beyond 100, while technically possible, makes it hard to balance the game out - especially the game is as long as multiple regions; or you force the player to start over in each new region, meaning you might aswell play every game in succession.
Not to mention how would you incorporate postgame sidequests - do you unlock the paths prior to completing the league? Do you just cut all of it out?When will you go to the next region? Right after finishing league, so basically literally no postgame? Do you put every region as postgame content, ala Kanto in G/S/C, letting the player decide the order? How would you balance that?
