Watching it as I work. Pretty cool seeing all the buildings and upgrade options for what they build. Saw earlier you can put down bus stations and then individual bus stops where you control where the buses go. If you pay attention they upgrades they do are influencing neighbors. A gambling HQ in one city looks like it allows neighbours to add advanced casinos without having to build one themselves.
"Going Green" city starts in just over an hour. Really looking forward to this one, seems like we'll see a lot of technology advances and useful tips/tricks on getting sufficient power out of non-polluting sources, as well as the usefulness of recycling... electronics?maybe?
