>>32729703I wanna add more to this.
I think if something like it were implemented, a second team would be a good idea too. They'd oppose the corporation, obviously, and initially appear as the antagonists. Maybe this second team would try to find/summon the regional legendary because they think it'll break the Corporation's hold on the region.
This team would be like a group of rebels, much more casually dressed and support the small vendors that sell herbs, berries, etc. to trainers.
At a certain point the player could learn the truth about both sides and have to help the rebel team. Maybe even another little twist where the region legendary was misinterpreted and it could threaten some kind of destruction that forces the player, the corporation, and the rebels to join forces, etc. etc. and eventually open up regular marts/grant access to the other items.
Just spitballing, obviously.
