It's really not the quantity, it's the time.
Remembering 60 thousand covers is easy, continuing to remember 60 thousand covers for 20 years without rebate is somewhat of a tax to my resources.
I'm not counting my digital comics.
I moved over to digital (exclusively) about 6 years ago, and that's probably doubled my collection, even though I don't really consider digital comics to be "real".
Does anyone else think that Kid Immortus is a piss-poor addition to the Kang Dynasty?
