So this week is the Game Developers Conference in San Francisco.

And a lot of it can be a little inside baseball... but one announcement might hit home for a number of our listeners: there is a new "SimCity" game on the horizon.

The game will be made completely in 3D, and is the first update to the game in around five years.
