Also, at this point, I don't think Pokémon is generally seen as a "video game IP" in the same way that stuff like Mario and Sonic are. Of course, it does originate from a video game, but it contains a vast number of sub-sections of the fandom, which don't necessarily overlap. I've known people who have solely watched the anime, played the TCG, or collected Pokémon plushies and lifestyle products, but have never even touched the games. It has a very large and diverse fandom, and it could have the potential to be an even bigger draw than Mario if it is done correctly.
