Hell, it's hard to write for this many characters. I can't imagine animating them all.

Seriously, have you ever done a roleplay with someone where you're each controlling multiple characters? I used to RP with a friend of mine where we had made up an entire world and thus had tons of characters. Whenever a lot of them gathered or we were doing scenes that were happening in at least two different places at the same time, it took some work trying to juggle all those characters.
