Gung-Ho and Gamearts will offer a pre-release demo for Ragnarok Odyssey, Famitsu reveals this week. The demo will be available on the 19th, a couple of weeks before the game's final February 2 release.
Outside of the demo news, Famitsu has a full preview, detailing some elements from the game's battle and growth systems. It looks like you'll be able to change your character's job once you've progressed a ways into the game. Also, the game's battle system allows for aerial moves. While in mid jump, you can move your character forward, back, left and right, and can also perform a downward thrust.
