Come on, 1.77 to 2.05 million..... that's almost 300k units.... 300k units is close to an averge yearly week for most systems. That means it's a pretty steep record.
14% increase.
that's like beating your 6 minute mile by doing a 5:11 minute mile. It's a BIG difference.
Numbers: Checker Players > Halo Players
Checkers Age and replayability > Halo Age and replayability
Therefore, Checkers > Halo
So, Checkers is a better game than Halo.
