Imperator: Rome - The Punic Wars Content Pack
This free DLC adds a lot of new mission trees for Rome and Carthage, while also giving us some new models for ground and naval units. And while I appreciate a free DLC, I don't understand why this wasn't in the base game from the start. The fact that greedy Paradox originally planned to give a big price tag for something this obvious and essential for the gameplay is fucking sickening to me.
