There is actually a full patch of the Chinese Haruhi game for PSP...well as an fan of visual novels, I really like this type of games myself, story and character development are pretty much why I would play the game.
So I am really look forward to this.
I read a bit of the kanji on there it seems like you can move around the maps but it's still a visual novels type, they've got the same program with Taiga's head that follows your mouse around. Same as the Haruhi one if you know what I am talking about. Under the TORA system tag
