The aim of Empire Earth 3 is to start with your cave dwellers and have them gather resources and construct buildings until they have enough resources to advance to the next stage in human technology. Eventually, you build your way up to future tech where you have walking robots and hyper-fast bomber planes. The problem is that there are other AI players in the game who want to dominate the map and destroy you. Advance your civilization while hindering and hunting your enemy. Most people state that Empire Earth 3 is not as good as Empire Earth 2, but the truth is that it is almost an identical game except that Empire Earth 3 has better character modeling, particle effects and graphics. If you enjoyed the Empire Earth 2, then do not bother buying the third sequel because you will not get much extra for your money. However, if you have never played an Empire Earth game, then you may as well start with number three because it has the best graphics.
