I have started a SPQR campaign and have funnelled a ton of cash into Carthage, but to no avail.... They were attacked by Spain and I took down the invaders and gave the provinces to Carthage but they have not advanced much at all, I think they may be busy with the Egyptian powerhouse so I think I will give them Spain when I am done conquering it, but not yet cause I need somewhere to build and stage troops.... I am using south east coastal province right now to stage a huge bribed Scipii army.....
Everybody should try the SPQR campaign because you can start civil wear first turn and bribe romans and then turn them into important members of your family or governors of their old lands... I love beating down the romans from the inside out...
