Now with fighting on horseback!
If you weren't already sold on JoJo's Bizarre Adventure: All Star Battle, perhaps just under five minutes worth of spiffy new trailer will convince you, especially since this one reveals that the game will feature all of the series' protagonists from all eight of its story arcs, all the way up to Steel Ball Run's Johnny Joestar and the lead of the current JoJoLion arc, "Josuke Higashikata" (who has the same name as the hero of the Diamond Is Not Crash arc).
Besides that, there's beautifully excessive anime violence, a top-tier Japanese voice cast, manga-style sound effect text, and a lot of characters voguing. Also two fab dudes fighting on racehorses, and more details on the "Gold Experience Box" limited edition, including closer looks at the Jotaro/Star Platinum statue and its apparent companion, a Dio/The World statue.
Namco Bandai HAS to bring this to English-speaking gamers. They have to! I don't care if they have to change everyone's names to remove musical and fashion copyright references (a lady named "Hermes Costello" is just the tip of the iceberg) to do it!
