Rome looks all set up to be a sprawling Empire of cities you either found yourself, or take with legions. That seems like a fair representation
.
Trajan's character model looks great, but his ability is a little unexciting. Don't get me wrong, it's a low-key but useful thing to have your culture buildings up right away from the beginning of the game. It's just unspectacular compared with some others, and not representative of the man's conquering history. Hopefully his agenda will be ruthlessly militaristic.
Legions building forts and roads was expected - but now they are built instantly! This makes Classical Rome really powerful in defence, and if they can be built outside of friendly territory, very strong indeed.
Also, as I suspected, they still get aqueducts built in their bath districts
