Thank you for a valid prompt answer.  Good night.  :)

But Wii Sports is not an actual game. It's just a tech demo. There is no depth to it. It's just a waggle fest. It's also bundled with the Wii. It also has Wii in the name. I don't believe that their is one cut scene in it. The graphics are blah. The characters don't have legs. You can't even play a nine inning game of baseball. The controls aren't 1:1. It's just a waggle fest. Metacritic ratings of it aren't very high. Metacritic is always right when it backs up my opinions. I just spilt some milk. I'm going to cry. Wah! Wah!

 You know what I'm starting to think? The less legs characters in a game do have, the more legs have the sales of the same game.

You might be on to something.  Rayman doesn't have legs. 

Yeah, and the legs of the characters in Mario Kart are hidden in the Karts...

 Not on the bikes though. 

In Carvival Games the characters have legs but are missing arms.  That has to count for something and probably does help explain the continued sales.  

All games that has been bundled with the standard console pack, should not be counted. SMB and Wii Sports would never have sold that many units on their own. They'd easily sell millions, but not anywhere near the astronomic numbers they are at now. I'd say a game like Nintendogs is the game to celebrate over. It's sold more than 21 million alone and it has expanded gameing to the fairer sex in a massive way. When these little girls grow up, they will be games, just like us. Lucky son of mine.

 I'd rather congratulate Pokemon Blu/Red... It has definitely sold over 25M (non-bundled).

Wii Fit, Nintendogs and Mario Kart Wii are all likely to beat that at some time though...

How dare you interrupt our discussion about the concept of continous sales of software, Mister N.Genckel?

@ nintendo_fanboy After playing Wii Fit enough, you will feel as though you have no legs, and this backs up your theory about games with legs.
