I feel like I just responded in a topic similar to this. I feel like years ago, I could tell you why I love Pokemon. Today, I'm not so sure. It has a lot to do with the fans input and it being a part of culture. The only thing I buy are 4komas or cute and silly imported Pokemon mangas, and that's mostly because the Pokemon are really humorous and full of life in those. It's like PMD but more interesting and way less serious.
I like to read/see other people's interpretations of Pokemon, as well. I also can't stop drawing them. Well, I can't stop drawing some of them, anyway. Okay, I can't stop drawing a handful of them. <_<
