On the topic of the Light-saber, Kumoriken, some mates at my Uni have said that if there is a saber game on the Wii, they will be getting one. I think there are a lot of people who share the same mind-set, and that would be a great benefit to the Wii.
Harry Potter... Well, I used to like it, but these days I don't really care too much for it. I got the first game a few years back when I was a bit younger, and I didn't even like it then. See the Box-art threads for my opinion on movie-to-games.
