The current game, "Hegemony Rome: The Rise of Caesar", takes place primarily in Gaul plus southern Britain and Northern Italy as you can see in the game map below. The campaigns in the game cover Caesar's invasion of Gaul and the breakdown of his relationship with Pompey that led to the civil war but won't cover the civil war itself. If the game is received well, we do hope to do some expansions but we haven't made any decisions on what those will cover at this point.
