It's been long enough since I last played an Ace Combat game that I can remember only two things about Ace Combat. And 2) you can 'powerslide' by wilfully initiating a stall, which I think might actually be a move from Tom Clancy's H.A.W.X. Delivery Must Complete sort of builds a whole subgenre around the thrill of powersliding planes. The clue is that "DMC" is also an abbreviation of "Devil May Cry". The story blurb suggests that your overall goal is to make a delivery.
