There are gaia gates in the 360 version. They're fun - I don't get why everyone hates on them. The best ones are the ones which require you to switch between sonic and the werehog segments to reach acts, like in spagonia. And there are 1-ups in the gaia gates. I know, because there's one in Apotos, across the bridge where the robots are. If you enemy bounce from the flying things, you can reach one. EDIT: Oh, I called those little entrance stages gaia gates, my bad. Yeah, there's no actual gaia gates like in the wii version. This is an improvement.
