An amazing expansion with more than what meets the eye!
Civ4 added many things but, one of them was the coroprations. They were a little bit of letdown to me but, there still nice. They basically set up compaines all over your civilization which prosper with money but, I really thought they were going to be more awesome than that. The game also added new buildings, factions, and units. The factions they added were pretty sweet. I mean the Ethopian and Dutch factions were really neat. And now every faction gets their own unique building. The space victory is much better because you can set up your ship and wait until it gets to it's destination. However, my favorite thing they added was the mods. Two of them completly changed the game. One basically puts you in the future where nearly no units or buildings were the same. Also the game just acts super different. The other just adds gods and other stuff to the game. All this comes with this expansion!! The expansion just simply is great. However, the espionage was a little lackluster to me. I mean theres spy and crap but, I was expecting more just like what I was expecting in corporations.
When I add everything up, if your a Civ4 fan. This is an expansion you just must buy! The game packs up much more new stuff and the mods they give are just too good.
