I just saw the latest trailer posted on the main site. If I didn't already have ready access to a Playstation 3, I would seriously consider buying one just to play this game if a Western release were announced. It looks like an animated film that you can play. In my mind this game is definitely a system seller. If it plays half as well as it looks, I can see this being a genuine classic.
The look of the game is just so impressive. Every time I see it, I can't help but think it was a labor of love on the part of the creators.
