Hi and welcome.

I suggest plan your next Roman campaign around a civil was kicking off around 40 regions. Plan it so your forces are gathered for the attack on the Romans. I tend to aim for Rome as the 50th as SPQR doesnt expand whilst the other factions do.

Senate offices I dont really understand. I had none in my Brutii campaign. The generals who hold offices gain positive traits and bigger bodyguards (more influence). I havt figured how to 'play' the senate office part of the game.

I played Julii on M/M, Brutii on H/H and now Egypt on Vh/Vh. At least as Egypt I dont have the civil war to worry about....but Rome will still be around region 50.

You might want to experiment with unit scale and graphics settings before you start. I recommend Large scale (Hastati=80men) and turn your grass graphic settings off (and the others way up).

Enjoy your next campaign.
