Harris revised the game for Milton Bradley in 1984 to be reissued under the title Conquest of the Empire as part of the Gamemaster series.

The gameplay in Conquest of the Empire shares similarities to Axis & Allies, another Larry Harris project within the same series.

Players begin with a Caesar, six generals, a small number of combat units (4 infantry), and a home province.

Players can undertake any number of actions during their turn, provided they can make them by not exceeding a legion's ability to move.

[citation needed] Allen Varney reviewed the 1984 Milton Bradley version of Conquest of the Empire in Space Gamer No.

[1] Varney commented "Conquest of the Empire is a superb contest of skill - not strong on simulation, but very good at capturing the grandeur that was Rome.

"[1] The 2005 re-release featured a tweaked version of the original rules as Conquest of the Empire: Classic.

Players now fight for influence in key provinces and troops are not limited in their area movement anymore.

New concepts include forced alliances, chaos points, action cards, and senate votes.
