[@Walulululuigi] Well ideally I’d want a bit more realism in the sense that parents don’t let their 12 year olds go wandering off on their own :lol In terms of changes the biggest would be the defeat of Team Rocket and the creation of the Oak Institute. The OI have made it so Pokemon flourish in each and every part of the world. This is so people can catch whatever Pokemon they want, where they are.

As for Gym Leaders and stuff, they will have moved on or retired. It allows someone to become a Gym Leader if they so wish.
