GungHo Online Entertainment only bumped Ragnarok Odyssey Ace back a little bit. The Vita version has been rescheduled from July 11 to August 29.
Ace is an expanded release of Ragnarok Odyssey with new Ace skills, more monsters, and the Yggdrasil Tower which creates random dungeons. Ragnarok Odyssey Ace is also in development for PlayStation 3, but a release date has not been announced.
Xseed released Ragnarok Odyssey in North America. Perhaps, they’ll pick up Ragnarok Odyssey Ace too.
