Summary: This was a great expansion, a lot of the new and updated policy tracks helped adjust some of the unbalanced trees. The reintroduction of Faith added a new way to manipulate city states. I love using the Celts and going for faith, they generate a ton right off the bat and being able to use faith to buy almost anything seems almost OP. Totally love this . Would buy.
Summary: This expansion took a bland and flawed game and really spiced it up to the extent that the game becomes a lot more interesting and playable. If you go the further step of also getting Brave New World, you'll have an experience that is far beyond what the vanilla version of the game gives you, and it suddenly becomes addictive and very worth it.
Summary: A great expansion pack that adds move civs, wonders, religion, and espionage to the game. Although, not really clear on what you can do with espionage to have that big of an impact on the overall game besides steel techs and rig elections in City states. Hopefully the next few expansion packs will truly give us a better gameplay experience.
Summary: I should have gotten this a while ago but enjoyed the base enough and there is plenty to do so I never picked it up. Spreading religion changes the game so much giving more play options as well as spies.
Summary: This is a sold DLC addon with a number of civs added, natural wonders, wonders to build, spies, and the religion system. However lack of a religion win dampens the going heavy into religion and if you are leading in tech spies are useless. It's a fun addition but not worth twenty-five dollars unless it's just spare cash.
