Played this game three times in a row...
First I played this game blind, and I fell in love with the story and setting, the experience of immersing myself into events adapted from the lives of Pompey Magnus, Julius Caesar, and Caesar Octavian.
Then I played on the highest difficulty, and I fell in love with the tactical combat, which is challenging enough to make building powerful characters really rewarding.
The DLC and the few remaining achievements convinced me to play a third time. If you can be convinced to play Expeditions: Rome even just once, I think you'll really enjoy it.
