Play 5th gen for the story, it's significantly different between B/W and B2/W2 so if you don't want to buy one of each pair buy B/W and later on purchase B2 or W2 (the story of B2/W2 takes place 2 years after B/W so you'd be missing on quite a lot of plot), keep in mind that many people prefer the story of B2/W2, also X/Y, the upcomin Sun/Moon and Super Mystery Dungeon !
