But even the tiniest Tacitus will be amused for only a little while. Even as you change maps, you won't get a sense of real progress. Once the short-term goals of the campaign scenarios are met, you are prompted to choose another city for more short-range goals.
Many structures are only doled out on a schedule; they're available only if you have met certain city conditions. While this gives this you lots of minigoals to meet, it also keeps much of your city looking identical. There are too few building styles and types to give your Rome a character much different from your Pompeii. If weren’t for the dramatically different landscapes, each city would be a carbon copy of the one before. It’s a shame there are too few maps to make use of the varied terrain.
