Buffs for Rome
There’s a couple mods on the workshop that attempt to make sure AI Rome becomes a worthy opponent. I’ve found that no one mod really does it, but a couple mods seem to do the trick. This mod is one part and gives Rome some really strong buffs. This mod greatly increases Rome’s income, food, research, gives them additional options for generals, and makes their cav generals the normal strength of 60.
In addition to this mod, I highly recommend using the Guaranteed Major Factions mod. VERY IMPORTANT: Use the custom faction feature to make the only major faction to be Rome. The instructions are in the mod (link below). If you don’t, ALL playable factions count as major factions so it basically doesn’t do anything.
I also recommend the AI mod Aucta Vanilla – Campaign. In my testing Rome always has done extremely well in expanding with this mod. Other AI mods would probably work too.
After 5+ test campaigns Rome has become a monster power every time. They are also fairly aggressive as well. Give it a go and let me know if it works for you.
