Paradox Interactive has ventured into Roman history before, but the result was the uneven, disappointing Europa Universalis: Rome in 2008.
They've dispensed with trying to make this a Europa Universalis game this time, choosing instead to allow the game some room to breathe in its own right, in hopes that they'll create something that will stand alongside their other historical strategy titles and possibly launch a franchise in its own right to go with EU, Crusader Kings, Victoria, and Hearts of Iron.
This doesn't excuse you from making Victoria 3, Paradox. Get on that.
Imperator: Rome will stretch across the known Classical world sometime in early 2019.
