The 360 version is my all time favorite game so i bought the Wii version. I got a five dollar gun for the wii controller.
I really liked it. I was surprised at how different the story and dialogue was and thought it was cool how the hotel manager and mayor look like they do in the movie.
I would get it. It's cheap and fun.
My only problem with the Wii version and with all wii games is that I get tired after 30 minutes from wrangling ghost all that time.
If your a Ghosthead I say get it.:-O
