I’ve seen video edits of games getting TV-style show intros before, but I’ve never come across one that used all-original animation before. YouTuber AmazingArtistYellow composed this truly excellent intro trailer for the as-of-yet unnamed Super Smash Bros. installment for the Wii U. But past that, he animated the entire thing himself, and compose an intro that’s similar to animes like Attack on Titan where it introduces each character doing badass things.
I highly doubt Nintendo would ever use such a thing in the game, but it’s damn good work and I would totally watch a Smash Bros. anime, now that I think about it. Check it out above.
