A Quick look at Hail Caesar - (a.k.a. Warhammer for History Nerds)

Hail Caesar is a game of tabletop battles with model soldiers set in the Ancients era. Pit your wits and tactics against your friends as your armies clash in combat on the tabletop.

Firstly, the most popular faction - the Romans, their main strength being heavy well armed/armoured infantry

Then of course we have their main adversaries, being what they would have called at the time the 'barbarian' factions.
Most prominent amongst these being the Gauls :

and the even more savage Britons :

Other 'non civilised' factions which are particularly adept at horsemanship included the eastern factions - the Scythians:

and their Sarmatian neighbours :

Besides the Romans themselves, other factions from the classical world are available, including the Greeks :

and Macedonians (notable for their pikemen-like Phalangites and formidable Companion cavalry :

Of course, once you've acquired enough troops, you can have a big bust up as below, and 'unleash hell' ;)
