WHAAAT!?!?!? ARE YOU SERIOUS!?!?!?!??!? ARE YOU JUST REALIZING THAT?!?! all pokemon versions are the same, you start and just moved into the town, you go to professor wathever house to choose fire water or grass pokemon, then you meet your rival wich choose the type wich is strongest agains yours, then you go to next city, buy some pokeballs, catch pokemons, defeat gyms to be able to use attack in the overworld, you learn them in the same order in all versions, meet an evil team wich want to do evil things, then you get to the league and defeat the four guys to be the best trainer, always two versions, only certain type of pokemon in certain versions, some time later there appear a third version wich is a mix of the two, each new version has 100 more pokemon than the last one, that is the only difference, oh and a new region.

EDIT: this says all that have to be said
