Like I said, classifications tend to rely more on type than anything. Well, type, evolutionary level, and Legendary Pokemon, but those guys are pretty scarce.

[That being said, Riku can understand the desire to learn more. Heck, he kinda embraced his own nerdy side over the ears.]

But, hey, if you're into that kinda thing, there's still a lot you can sink your teeth into. Legends, old landmarks, that sorta thing.
