Hey everyone, I stumbled across this awesome game series a few years back called Hegemony Gold you can find it on steam. I will provide links. You can Find Hegemony Gold and Hegemony Rome on Steam. That said they are running a kickstarter campaign right now to fund their next title. It looks awesome! They did a live preview a few days back. Which you can find below.
That said this is not StarCraft in the sense that it is a fast paced RTS. But more a thinking mans RTS where you have to capture / raze settlements, establish / maintain Supply Lines, Think about troop placement and play to your troops strengths. They even have mod support in the form of an editor (Which will be made available to modders) and a bunch of other stuff. With that said they have a large scale map of the Italian Peninsula. Set prior to the rise of Rome. You can find the Kickstarter here Have an awesome holiday season. - Headclot
