As we close out the week it's time to pull the curtain back on the last part of my Aero the Acro-Bat retrospective exposé.  Today's installment is a real coup for us at Kombo, as Aero's creator, David Siller, generously offered up the original rough draft concept document for the original 1993 Aero the Acro-Bat video game for the Super NES and Sega Genesis for me to analyze over at Kombo.  You can read the entire document from start to finish and check out a little commentary from Siller and some interesting notes from yours truly.  Then, after that, we have some rare promotional artwork of Aero in action for you to see.  It's not often that we get a close look at the origin of a video game from that era, so this really is interesting reading.  Many concepts from the original document did not make it into the final version of the game, while some of the final version's elements are not listed in this document.  It's fascinating stuff and I hope you all enjoy digging through it as I did.  Feel free to spread this one around to your friends, social networks, and favored news aggregators along with yesterday's piece.  Everyone who enjoyed character-based 2D action platformers from the 16-bit era needs to see this.
