Ace Combat 7 all the GODDAMN WAY. I liked the trailers for that game so much and was so unbelievably hyped with this it that I ended up making a youtube playlist to watch them all on one go.
Speaking of Ace Combat, someone must be as crazy as I am for this series because they turned one of my favorite game trailers ever, the E3 2006 one for Ace Combat Zero, which also serves as the intro for the full game, into an animated sequence using footage from the Area 88 OVAs from 1985.
Original trailer:
Animated version:
I like this video specially because it evolves into a crossover of its own. Ace Combat is very obviously inspired by Area 88 and other militaristic series from that era like Macross and Gundam. The thing is, Area 88 already had a great videogame adaptation in 1989 developed by none other than Capcom! And that was released in the west as U.N. Squadron.
I like to think of this video as the two series going full circle.
