Yes, Sid Meyer is the master, but this game was made by guys that learned his lessons very well! And, they are even better than Sid in some areas!
This is a great CIV game with hundreds of units, buildings, technologies and a sea of options available. I truly appreciate the UI, way the best ever made for a CIV game, simple and effective! Diplomacy offers a wide array of agreements, even if AI is not so competitive.
The possibility to colonize the oceans late in the game adds a new dimension of exploration and conquest to the futuristic era. I also appreciate the fact that scientific victory is as easy to achieve, the player needs to control a good portion of the planet making diplomacy or conquest a must.
The previous CALL TO POWER had even space cities with orbital bombing, too bad that this is missing here!
