Edge writes: "Nintendo's Mario Kart Wii and Wii Fit have each sold over one million units in the UK, according to ELSPA, putting both titles in the company of a select group of games which have achieved the milestone.
Mario Kart Wii and Wii Fit join a handful of other UK 'diamond-sellers' such as Grand Theft Auto San Andreas, Brain Training, The Simpsons Hit and Run, as well as Mario and Sonic at the Olympic Games. Nintendo has now published four Wii games (and three DS games) which have sold over a million units alone."
