The second season of HBO’s Rome covers this period reasonably well. I’’ve got and old Avalon Hill game Trireme which covers the Naval Battle, and a variety board game wargames from SPI and other publishers which cover from the days of Egypt and Babylonia to the Fall of the Holy Roman Empire. It’s tough to beat Roman Infantry when they have even a mediocre General, and Octavius hand a great General and solid ally in Agrippa.
I really, really disliked the 2nd season, and overall I enjoyed the whole thing (reach exceeds grasp and all that), but it was only vaguely-based-upon, whole-cloth historical fiction.
For example, the real Atia wasn't the opportunistic libidinous trollop of the series, and died in 43 BC, hence wasn't around to see the paraded corpse of Marc Antony (another fiction, he and Cleo probably slid into the Med during a medieval quake) when he died in 30 BC.
The delightfully nasty Quintus Pompey character is a fiction (there were some men of that name, earlier on, and not a son of Pompey the Great).
Making the whole series a buddy movie was a great idea, and I love how they dealt with Octavian's contract out on Caesarion.
