Cam DeGray has released version 2.0 of his map Giza: Valley of the Kings (available at The Mill). This is a very nice looking map with some new models, including Egyptian obelisks and swank palm trees. Attention to detail is the order here and the map even includes an excavation team, which of course, you can kill.
As for unit balance, I can't comment but there are new and altered units available. If you've got the time, The Mill has the plugins. Feel free to grab it here.
