I know there was a thread about this before, but I have no idea where it's at now. Trust me, I looked.
Anyway, I happen to be a fan of Digimon. I don't know why everyone calls it a ripoff, because last time I checked, Pokemon didn't have any creatures that could revert back to their previous forms or switch between human and creature forms. Also, the Digimon didn't fight for sport. They fought to save their world.
They're more different than it seems, but quite a few people still accuse them of being ripoffs of each other. I don't get it.
