This is definitely a different type of game than what most are used to. You are immersed in a completely living world where you can do everything from buy toys from the vending machine to running a sidewalk gambling stand ("How about a game of Lucky Hit?).
The music is absolutely beautiful. You could just stick the disc in and listen to the soundtrack all day in my opinion. The only reason I don't really give this a high score is that it is less like a game and more like watching some dude walk about Hong Kong, which is actually kind of cool.
