All-in-one city scenery updates to recommend?

After downloading the Flight Ontario's massive freeware scenery for the Greater Toronto Area (my old hometown) I was very impressed. Are there any other similarly extensive scenery packages (labours of love) for other cities around the globe? I'm not talking about just an excellent airport, or a few well-modeled buildings, but a complete combination of ground textures and 3D objects that approaches the detail and fidelity of the Flight Ontario effort.
