There is a LOT of Fate Zero fanart floating around

Viani

I was wondering, do popular anime generally have this huge of a fanart wave, or is Fate Zero promoting it with a art contest or recognition community crunch or something?

Popular anime generally have that much around them, yes.

Do a search on any booru for any popular anime series, and note how many results there are.  And also note when each came out of course.

But the answer is, yes.

Also the Fate/ series has been around for a while already.
