Dunno who made this, but it's perfect:
Pat's contention seems to be that having someone who wasn't the original creator of a character write that character is "wrong", which doesn't seem like it's that big of a problem with Gundam (disclaimer: I am not a Gundam expert). That's why he's okay with different people writing Final Fantasy 6 and Final Fantasy 7, but not really okay with different people writing Final Fantasy 7 and Dissidia.
That, from what I can tell, is his working definition of "fan fiction": when anyone other than the original author writes new content for a character.
This is funny, because technically, with Gundam: The Origin and Zeta Define, which were
not written by Tomino, but basically rewrite the original and Zeta Gundam, UC Gundam is now fanfiction.
Also, technically, Star Trek is technically fanfiction since TNG season 3, when Gene Roddenberry started getting super sick/old and stopped fucking over the writers... aka when Star Trek started getting good.
