Do all the fun stuff, e.g. hang round with those fan-fiction dudes in uniform, play all the splatter/bloody games, test games you would never EVER buy, try the latest version of SingStar & just be epic!
Best time is when it's uncrowded, so go and get the ticket for press visitors/ the cool guys (it's good to have friends that have the vip-connections) one day before the actual exhibition begins. Plus, the most epicness is reached if gotten the ticket FOR FREE. The evening could end with the caviar-and-champaign-chillout with some of your new game development/promo -friends.
