Hey there, Hawkiel! Welcome to PRO. :)
Having been around PRO for a very.. very long time, I can tell you that this game has an amazing group of people working to bring constant content updates. If you've been to Kanto and Johto before, you'll recognize quite a few differences from the traditional handheld versions which have been tailored to suit the MMO environment.
Enjoy your journey, and good luck!
Yeah, i know all the pokemon game extremely well, and ive defiantly noticed differences, but the differences are amazing, i like it alot so far, and i cant wait to get further in game.
