DoA gets recognition because it saved Tecmo from fucking dying. Tecmo put everything on DoA, if it had failed then Tecmo wouldnt be around today. It took a few simple concepts made them work and created one of the most recognized and succesful fighting game series' ever. Thats why it gets recognition, because it single handedly saved a company. Not many games get a chance to do that, or actually succed doing it and then some.
I watched it when it was on. It was pretty cool because they gave a "tour" of Team Ninja, if you even wanna call it that, and Tomonobu Itagaki basically called everyone who made nude hack for DOAXVB fucking pathetic. LOL. Also, he spoke briefly about what to expect for DOA4 and Code Cronus
EDIT: Tomorrow on ICONS they have something about the history of video game music, so that should be cool.
