I thought it had a little more than 2 miljoen sold :s..

In the States Wii Play is still $49.99 (including a wii-mote), Sony's Plantinum line is $19.99 or lower.

... so it costs mere $10.

 That's how I feel. Also Wii Play is counted, and it's not a retail game in the states. It's a demo exclusively packaged with the Wii. As I've said before. Package games werent counted for the PSP, why should they be counted for the Wii.

Randomly packaged walmart games weren't counted.  Those packages never sold enough to make a blip on the radar anyway.  Wii Sports is sold seperately everywhere but the states, and is still on it's way to being the best selling game of the generation.  I'm sure you'll understand how important the game is when Wii Sports 2 comes out.  It would be purchased even if it wasn't packaged.  It's a large chunk of the Wii's appeal to the casual (the Gran Turismo of the Wii so to speak).  Europe and Japan are proof enough the game is huge.

 In Poland Wii-Sports is bundled too.

 I think it's bundled everywhere in Europe (certainly in the Uk too)

er... k.  I guess one small second market has it bundled too.

 I've checked it. It's bundled everywhere in Europe.

Wii Sports comes bundled in Europe and Australia. The only place where it doesn't is Japan. Check Wikipedia if you want, this is so common knowledge that I'm not even bothering to dig up a link for you.
