Producing a game is like building a house.
Once you start going, you lay the foundation, get all the tools, the labor, get the frame and structure going up, it's hard to switch gears and start a new house.... you could just abandon what you're doing, but that costs a lot of money and time.
Logically it will take months to even a year for a gear-change, or a philosophy change from producers to occur. Some are already phasing to a new idea that Wii should see more games based on user base. I don't think we'll see 'great', amazing games that people remember for years until at least next summer or winter, by 3rd parties... we're talking, the epic blockbusters that take a year to a few years to produce/perfect.
Numbers: Checker Players > Halo Players
Checkers Age and replayability > Halo Age and replayability
Therefore, Checkers > Halo
So, Checkers is a better game than Halo.
