An amazing real-time strategy with solo campaigns, LAN and Internet play.
Chose one of many races and build an empire !! It is insanely great.
From Inside Mac Games:
Gameplay is pretty smooth. Your first task is to build shelters for your tribe and begin collecting raw materials in the form of wood, stone, gold, and food. You will need your villagers to gather all these supplies. Did I mention you should read the manual? Anyway, begin gathering and building. Once you build a barracks, you can begin training military units. In order to progress through the ages (i.e. Stone Age, Bronze Age, Iron Age, etc.), you have to achieve predetermined levels of raw materials and build the prerequisite buildings for each age. When you advance to the next age it is rewarding to see your buildings change in appearance. Why? I don't know, maybe I need to get out more. One piece of advice: when you can build a temple, build it. Training a priest is the only way to heal wounded units. That last only applies to living units. Don't use the priest to heal buildings. It will not work. Use villagers for that purpose. Another advantage to having priests is they can convert enemy priests or any other enemy units.
