I think Nudge explained it very well. I thought Ghost Trick was quite good. It has the same wackiness of the PW series with some ridiculous characters, lots of story twists, and a great sense of style. It is more puzzle-y than Phoenix, so it isn't exactly the same kind of gameplay. Given you can download the beginning for free, anyone remotely interested in adventure titles really should at least try this out and see if they find it appealing.
