While waiting for true ingame videos of the game (when I actually understand the game system), here are two videos from the demo of Phantom Dust distributed in the latest Famitsu Xbox. The first one is the actual CG only intro, the second is from the attract mode and present a mix of CGs and amazing ingame footage.
I've not been able to play the game much yet, but so far technically and artistically Phantom Dust really impressed me. Can't wait to have someone helping me a bit so I can make some more videos.
