Sudeki has been annouced almost 2 years ago during the X02, and was said to be a just like a japanese RPG, but developed by english developers. If you can just forget that statement and play that game more like an very action and exploration oriented game with some RPG elements then you should be able to enjoy the experience like I do.
The video is in french, you have been warned !
Video done with an import US version. The european game should be exactly the same.
