You take control of a civilisation during missions. Each of them has different features: some can access a particular technology the others can't. You control civilians that will build, hunt, fish, cut wood, bring gold/stone, etc.. You can also order to buildings to produce a specific unity. Also, you will have to build an army for defending and conquering your enemy. You can also make trade with your allies without forgetting that you can also explore the seas with boats. Your goal is to win but for doing it, you will have to advance in age. You have four ages and each one bring new buildings, new technologies (you'll have to develop them for improving your civilisation) and new units.
