I'm already hooked.

They've done a great job of having each turn go quickly enough and making you want to play...just...one...more...turn.

The controls are simple and it keeps any maintenance hidden from you and goes back to a city when it's ready for it's next action.

I usually start to get overwhelmed with options in a game like this since you can play SO many different ways and have various victory conditions. The thing they did that entices me is setup the Achievements so that it helps give you structure and goals to complete the game with various leaders and with different conditions. Now I'll have a reason to play on Deity, with Abraham Lincoln, and win a culture victory... I'll get 3 achievements for it!

I'm anxious to try out the multi-player so let me know if anyone wants to give it a go.
