It's the same game right? Well, sort of. Though they may be the exact same, game layout wise, the contents are totally diffrent. Sound confusing to you? Each version has a diffrent arrangement of Pokémon in it. Your goal is to catch all 150 Pokémon, but how are you going to catch 'em all, if it's different between the two versions?? Trading my friend, is the key element that makes this game so great.
