Pokemon has always been extremely popular and the franchise itself is great at retaining its target audience . Their products are steered towards children such as the anime , but Pokemon cards and their video games are complicated enough for adults to stay interested . Pokemon Go was a success for younger adults who grew up playing RedBlue to reenter the market due to the nostalgia effect . Also millennials have a way of making things that are perceived childishnerdy for a lack of a better term cool . The new release of Sun and Moon was a strategy of retaining their current target audience and obtaining new audiences people who have never played or quit playing newer gen games . I am 23 and for as long as I can remember , Pokemon has always been quite popular and I don ' t see that changing anytime soon .
