Civ Rev is a great strategy game. Even casual strategy fans should give it a try. It is turn-based, so you can take the time to learn. Perfect for first-time strategy players.
The game does allow some micro-management of your cities, but nothing too complicated that would take the fun away and make playing seem like going to work. The graphics are not great, but they serve the purpose of the game. There is some slowdown later in the game when you have a lot of military unities, but they are just annoying - again, this is turn-based, so you are not going to lose battles because of them.
There are many civilizations available for you to play with and each gets unique bonuses, adding to the replay value.
