The models and atmosphere of the 2006 and 2007 Tokyo Games Shows and other events. The first saw the introduction of the much-hyped Sony Playstation 3, whilst by the time of the latter the Wii had paradoxically won the 'most popular console' distinction, with the other two battling it out. As well as the games and models, there are always a crowd of 'cos-players', dressing up in the costumes of their favourite game characters. You could call them the heart of the show, as they take the games so much to heart.
Note- More recently, the addition of some other girls in 'cosplay' outfits from the Tokyo Dream Cosplay event. I'm not really a cosplay freak myself, but there were some attractive girls to meet and photograph and seeing the alternative culture in Japan is always interesting!
