Ghost Trick, Capcom’s upcoming supernatural puzzle / mystery game is hard to describe. Many of those who have gotten a chance to play the game have walked away impressed and wanting more, but often have trouble putting into words just what the game is. Capcom figures that the best way to explain it to you is to show it to you... which is exactly what they are doing.
The Japanese website for the game now has a
playable flash demo which will give you a sense of what is in store for the final game. Granted, the demo is in Japanese, but you should be able to figure things out and make some progress. Hopefully Capcom will release an English version of the demo soon so that you can get the full experience.
