You can play as 2 ancient era power empires in a new scenario

Interesting scenario based in the viking times, unfortunately, doesn't add any new civs, but adds new city states

So I tried playing as Japan and became a constitional monarchy and even joined the Allies. This became one of the strangest vanilla Heart of Iron IV experiences I've ever had. When I went democratic I pretty most lost my entire navy as the facist and my forces fought a violent civil war. I guess it's not a huge loss since I have the British Empire as an ally. While that was happening a random rebellion breaks out in the Soviet Union. I find my army fighting Hungarians and Croatians in the Balkans while the rest of my army fights the Germans in France. Things were going well until Italy joined the Axis and we have no sign of US help for a while because world tension was below 70%.

In other words I had no idea how this was going to turn out or what would happen next which made this one of the best experiences I've had in HOI IV.

It is a good DLC adds lot's of content and makes the expirence in Asia far more intresting and challenging

If you liked the Far cry 3, you'll probably like this one too. It has some new features like, you can drive a helicopter, you can pick up a body and drop it again, autodrive option etc. which is good but it lacks a story of its predecesor.

The unit sprites, especially the eastern women are kind of generic looking compared to previous sprites, which is kind of disappointing. I mean the Mongol intrigue person has an eagle on her arm. The female Africans are slightly better but not by much. The Byzantine clothing is ok.

Too expensive if you don't play in the Middle East (I do play in the Middle East, though, so personally I'm fine, but I imagine not too many folks play Timurids or Qara, so, there's that). But only *slightly* too expensive in that case.

That said, the change with Army Professionalism/Drilling is probably not being recognized for being as big as it is, even despite the attention it is already getting.
