This game was disapointing for me, because it's just not a civilization. I was expecting civilization game like the cilvilization II for the pc cause it's thelogical step. Insted we got a game more similar to the snes civilization home version from the 90's but whith prettier grafics and whitout the custcenes.
The game system is radically changed to make it more fluid and quick, culture plays a great part in the game since it trigggers the great people that gives you boost to your city's and great development advantages, culture also limits your control over the terrein very useful when triying to absorb enemy towns. The enemy ai is good but has it's flaws, I played the game for 3 days and I alredy found holes in it even in the hardest dificulty,flaws that makes the game much more easy.
That added to a short reaserch tree and lack of many wonders makes this game enjoyable but not to the replay standar of other games of the franchise.
