The game development industry has been busting at the seams with buzz about game development for cell phones. But what about games for the telephone everyone has at home?

And I'm not talking about odds-based contests, where you may or may not win a prize depending on if you're the lucky caller. I'm talking about games that people actually want to call in and interact with on a daily basis -- for fun.

Think about the potential:
* Everyone has the required gaming console at home (neither Sony nor Nintendo can beat that).
* People are familiar with the interface and may already engage in fun via phones (e.g. chat lines, walkie talkies, etc.)
* Inherent ability to support a multi-player environment (everyone is calling into a central location, can have a DB, etc.)

I believe the market is just waiting for the first killer app, and then this unknown industry will break wide open.
