And now for the ultimate reference site on the Roman Army: Red Rampant. This has got wonderful illustrations for just about everything you can think of relating to the Roman army and its enemies. It’s like an Osprey book, only much, much cheaper.
Jim Naughton has written a set of campaign rules for DBA
about the last stage of the Roman Republic. In it, each player will represent a Praetor, the second rank of Roman senior magistrates, and the lowest rank empowered with Imperium, the power to command Roman armies and exercise governorship of a Roman province. Eventually some praetors will advance to the rank of consul, and occasionally dictator. Ultimately the goal is to amass sufficient prestige to stand unchallenged as First Man in Rome.

The battle of Cynoscephalae in 197BC pitted Greek phalanxes against Roman legions. This scenario recreates that battle for the Vis Bellica rules set.
Jeff Jonas has an article on using war machines in Warhammer Ancient Battles. There are some nice pictures of painted Roman war machine models, and a good discussion of their use by the legions.
The I Live With Cats Blog has a variant for Lion Rampant featuring Late Romans.
