The game provides you with elements you may know from the "good old" Warhammer, the story is fine, the 'world' is fresh and interesting, but most of all, it contains a system of battlefield management which I find innovative and amusing. You can give only as many orders at one time as you physically can and just no more. It's reflected by number of messengers you have. Once the order is given you need to hope it was the right choice, as you will wait a while until a messenger is ready to go with another one. The battlefield is dynamic and full of surprises. That gives you quite a scent of a real 'medieval style' battlefield.
I think this one was most interesting and fun. The battles are not boring, there are some unexpected twists during the scenarios. I think I didn't have here a conclusion that 'the authors could do better' like I had e.g. in the Allies Resurgent campaign - when you have a huge map full of nothing and you just have to walk through it (seriously, that's how the authors saw Italy). This one is fun.
This DLC had a highly promising start. Early scenarios are interesting, makes you enjoy the play. However later on, since Tunis I think, it clearly seems as if the authors had too little time to complete the scenarios. For example, you receive a huge map, huge operational capacities but... there are huge parts of map where lies nothing. There is just a "uninhabited" terrain. While we could, let's say, justify that in Tunisia, like, ok there is nothing military important here, so we don't put anything meaningful on this part of the map, it's completely surprising in italy. In Italy you got a blank space of map literally going through the whole middle of the peninsula - there is nothing - your units can just move forward, go and reach the end of the map without encountering the enemy. And in the last scenario where you conquer Rome and Monte Cassino, there are no Poles to take the Cassino hill.
