If you are in, or around, Melbourne this weekend you may want to head down to Federation Square for the global launch of the latest driving game for the iPhone. Unlike a lot of iPhone applications doing the rounds at the moment, the CityGT game is available for free.

In what is being billed as a world first, the creators are giving people the opportunity to play the game live on the big screen at Federation Square. Ever wondered what it's like to play a video game on a 40ft wide-screen? Here's your chance to find out.

It's not often you get something for nothing these days, so I'd suggest that you take full advantage!

Here are the details (from the press release) for those who may be interested in giving it a closer look

The game was created by Melbourne-based advertising agency, JWT, and offers the best driving graphics available on the Apple iPhone for free.

Join the driving fun at the global launch of CityGT at Melbourne’s Federation Square on September 6th between 11.00am-2.00pm. Have a go at CityGT on an iPhone and show off your driving prowess by playing on the big screen.

Go to the City GT website to find out more about the game before it goes live, and then go to www.apple.com/iphone/apps-for-iphone/ from the 6th September 2009 to download the CityGT game for free.

Edit: A video of the game testing at Fed Square is now on YouTube.
