"Mario and Sonic has made gaming history with over a million software units sold on the Nintendo Wii within the UK alone," SEGA Europe North MD Alan Pritchard told MCV. "The title has been an immediate hit from launch and we will continue to re-invest and market this title throughout the rest of the year with a hope of reaching over two million sales by the end of our financial year."

I bought this game as a replacement for the party gaming provided by Wii sports. I'm not sure that it's sales success quite reflects the quality of the game. That said, I also think that it deserves a better metacritic score. So I'd say it's a slightly above average casual game. I'm sure this game will continue to do well for some time.

N.B. I believe the sales figures are for both the DS and Wii versions.
