Couldn't find an outlet for it. Originally it was supposed to be something for Cereal:Geek, but the editor and I had different ideas as to how it should be done and midway through we both picked up new paying gigs (I write for the Ninja Turtles comic books, James does a ton of awesome stuff – I think he was called over for the commentaries on the RGB set at the time). I've been slowly working on them since, but life being life, things got in the way and I had to focus on paying gigs.
That said, I've actually drawn up a shitload more of these, and there was talk a little while ago of making them an online feature at either GBfans.com or Protoncharging.com if we couldn't find some way of getting them out there physically. The original plan was to have say 5-10 appear in Cereal:Geek each time.
Haven't had a chance to work on them in a bit though, as I've been working on the Mirage TMNT comic sourcebook and a couple of graphic novels of my own. Interesting tidbit for anyone out there who cares – I was actually asked to pitch for IDW's Ghostbusters comics. The Displaced Aggression pitch was taking forever to get cleared by Sony, and they were worried it might not have gone through, so I was asked to put forward a story should it not work out. Displaced Aggression came through though, and I'm glad it did, because it's a great book so far!
