A small aside on the numbering issue, I'm pretty certain (and correct me if I'm wrong) that the first 20 Shameless releases (Wave 1) produce the Shameless spine builder. Any releases after that are just numbered, for no other reason but just to detail which release comes next.
I fully understand why people would feel compelled to buy the 1st 20 releases, but anything after that is just a number - no need to buy them all if you don't want to.
Most companies release titles with some kind of serial no. identifier on the spine, but how many people actually collect every title from that specific company just so they run in sequence?! Just because Shameless' numbers are more obvious (and lower due to them being a very new company), doesn't mean that you have to buy them all.
How many people will be worried about numbering when they're up to spine no. 1835?
