I think this is smart on google's part, I mean they are already considered the internet by less knowledgeable people, now they are hooking you up with a cool way to customize what you are using most of the time you access the internet, their site! Anyway to make people feel more at home and more comfortable is bound to work and just in time for Comic Con. I don't know but whoever they have running events for the little google titles must be having fun (not that it would be all that hard to do) but giving props anyways.
So they also have some nice iGoogle game themes to featuring Mario of course, Megaman, World of Warcraft, Streetfighter
