New markets like China and India will help Wii sell more than PS2, I think.
Speaking of China, how much did the iQue sell?
PS2 has been available in China since December of 2004.
India I'm not sure on.
Numbers: Checker Players > Halo Players
Checkers Age and replayability > Halo Age and replayability
Therefore, Checkers > Halo
So, Checkers is a better game than Halo.
