We got ours with the sports game at Argos for £179 which is a good price! We had to shop online for an Argos that had them in stock. We drove to Rugby to get it!
I'm not sure if the games are universal. I'm trying to find out now.
GET ONE!!!
I think that the games are region free, I know they are for the DS. Ok here's a little quote, a bit old but should help.
"UK, September 14, 2006 - First-party games for Wii will be region-free, according to NoA's vice president of marketing and corporate affairs, Perrin Kaplan.
Speaking to Wired News' Joel Johnson, Kaplan confirmed that, like the DS, Wii gamers will be able to play titles from different territories without restriction. Traditionally, games purchased in regions such as Japan, US and Europe have only been playable on native home consoles. The news is likely to be welcomed by import fans, eager to get their hands on games as close to initial release as possible - however, Kaplan also suggested that region-locking on third-party games would be left up to individual publishers. Currently, it's unclear how Nintendo's region-free policy will affect the playback of existing GameCube titles, which are fully compatible with the Wii."
