FreeCiv
If you happen to be a pretty demanding gamer, and love to be given a complete list of game features and options that you can explore to extract the maximum pleasure out of a game, then FreeCiv is right up your street. You need to erect cities and make a government. Apart from that, you have the aim of creating a powerful army and work towards making your civilization a strong and sustainable one. The multi-player option makes playing FreeCiv all the more interesting.
