For this second period I have already selected some good sets of rules - free solo friendly rules Ancient Battlelines Clash by Shaun Travers are definitely among them.
On the other hand, I have too many miniatures for all periods and scales, so I definitely needed something quick, dirty and budget friendly. Therefore, I decided to go with the paper miniatures.
All Romans are taken from Junior general web page. Picture above shows more than 110 points of Polybian Romans according to ABC points system, that should be enough to play even very large Roman civil wars games.
While Junior General have some nice Gallic warbands, there are no good miniatures for cavalry or chariots, so I had to turn to commercial sources - Lvmenes has a good 2 part set of Romans and Gauls.
So far I have made 35 point Gaul army. I will have to build more warbands in order to field larger force.
I will add some battle reports soon.
