"To celebrate the opening of Game On, an exhibition of the history of video games at the Australian Centre for Moving Image, Melbourne, from 6 March-13 July, we are giving away tickets to the biggest geeks around. All you have to do is tell us in 500 words or less about your best or worst video game moment. Did you beat your sister for the first time at Sonic the Hedgehog, meet someone special in Sims, or die just before finishing the last world in Mario? Whatever it is, we want to know."
