the one thing i would really like is to be able to play from kanto,johto,hoenn,sinnoh and isshu/unova, and be able to get all the badges from each region, maybe after you get past a region something terrible happens like team rocket stealing your pokemon or using some items to make your pokemon weak so you have to train then all over, yes i know it would get annoying but also fun in a way i think. some online coop-ness would be nice as well.
