Re: Too easy
Like punj, I'm surprised that you found the initial challenge easy. I'm playing a vanilla Carthage campaign and it's both challenging and enjoyable, I commented on it here.
Because you posted this in Rome II General Discussion, it seems that you are saying that the Rome II Grand Campaign for Carthage is too easy. However, in my Carthage campaign, I don't have the Punic colony buildings with diplomacy modifiers you described, money isn't rolling in, both my client states have been almost detroyed and I'm under attack on three fronts. It's not too easy for me! I wonder if the problem relates to a mod which you're playing, as others seem to be suggesting.
