"Let the Games Begin!"
The historical Roman Empire presented in GURPS terms. Covers the history, geography and daily life from the founding of Rome to the end of the western empire.
Historically based, a section does present rules for a fantasy-based campaign, detailing the religion of the times and the appropriate magic for such a campaign.
A whole chapter is devoted to the games of the Roman arenas – from Gladiators to Chariot Races.
Also has a chapter on the Roman Legions, including their history, organization and life within.
An excellent reference on the time period for any game.
