An AOE refill
You play three different dynasties: Japanese, Chinese and Indian. All offering unique units and buildings, but basically what you have seen before with new graphics. Some memorable units are Ninja's and the flamethrower. Both powerful units that will shift the balance to your favor, and its nothing more satisfying than seeing a crowd of enemies being torched by the flamethrower and saving the day. The main characters also has some interesting abilities this time, like a powerful bomb which can be thrown long distances and make the enemy fly in all directions.
The various missions are quite varied, and runs pretty well. Although in a lot of cases its very clear the designers meant for you to play it in only one specific way, and if you chose another way, for example by building a town center ahead of time or destroying enemy bases out of order from the narrators suggestions, you will be left with the feeling you played the game in the "wrong way". But unfortunately, the "wrong way" is often better than the "right way", and you will be left with a feeling of cheating if you ignore the narrators nagging you to do something in a specific way.
There are also a lot of new cards. I was never a big fan of the cards system, maybe useful in multiplayer, but during the single player campaign they do not seem to have any major impact on the gameplay. In fact, I stuck with the default deck of cards most of the time, and it will get you through the levels easily. So, in my mind they should have spent their time on improving the game instead.
The game is pretty long, and seems longer than the previous expansion. And I found the story to be more interesting than in the original game. Having said that, the original story was a big long yawn for me, so it's still nothing special, and the voice acting is at times very poor.
Graphics wise its as you would expect. Polished animations and structures, but nothing new. It's the same old engine without improvements.
All in all, its a decent add-on with a lot of new content, and I enjoyed playing it for the most part.
