Played with Augustus 3.1.0. Historical saves included.
Good challenging start to the scenario. Don't be deceived by the decent amount of funds initially provided! Although the attacks are light, the invasions still start quite early in the game and you will need to spend lots of funds on military.
In my first try, I wanted to feed everyone with only fish along with Pantheon access to reach to Grand Insulae level, which I eventually did with some palaces too, but I had a big challenge feeding everybody when approaching the population goal.
So, I restarted the game and this time I went with 2 types of food for all Grand Insuales, plus wheat import for the palaces. It turned out great.
Final note that you have to be patient with your grand temple and monument constructions since marble and clay are quite scarce. But all constructions are possible with enough patience and planning.
And the map design is so beautiful, you don't want the scenario to end! One of the best maps I ever played.
