I've spent most of my morning cleaning up a mess that revealed a much larger issue.
Here's the issue. Just because a character makes an appearance in a certain game doesn't necessarily make that game part of that character's franchise.
This started by someone adding every conceivably related franchise to the Super Smash Bros. game pages. For example, they were adding The Legend of Zelda, Metroid, F-Zero, Donkey Kong, etc. to the Smash Bros. pages. Yes, characters from those franchises appear in those games, but Super Smash Bros. is not a game in the Kirby franchise. No one is going to say "Smash Bros. is my favorite F-Zero game."
I hope this makes sense. Now, back to cleaning up this mess.
