This is an old extension play of RTW where the factions are Alexander the Great and Persia.

You begin with two cities, Pella, the capital of Macedon, and Sparta.

You also begin with two generals, Alexander, and one of his great Macedonian Generals. Alexander is in Europe while his Macedonian counterpart is in Asia Minor. You have four fleets and some armies.

The key here is twofold. First, Alexander must secure the flank behind Pella by conquering the two cities to the rear of Pella. This must be done rapidly.

Second, the army in Asia Minor should proceed to conquer the first city as soon as possible so as to begin to build both fleets and armies in Asia Minor.

It's important to realize that if Alexander dies, you lose the game, so do not risk Alexander unless you have favorable odds. On the other hand, he nearly always wins.

You do not have siege weapons, so you have to wait out sieges.

The navel aspect of the game is important. You should pursue the same strategy as Alexander--proceed along the coast, and strangle the Persian navy by capuring all of their port cities,and building fleets to blockade them.

One minor note--take Sinope on the north of Asia Minor, as it is a port city. Remember, the object is to build fleets, and block out Persian fleets.

Once Alexander is free, he should come over to Asia Minor on a convoy and begin the coastal route by staying to the oceans until he has come around to Egypt and captured all the ports.

Once all the ports are sealed off, the Persian Navy is limited to what exists at sea, they cannot build further, and you can blockade them from any convoys.

At this juncture, you are in control of several port cities and have built up the towns and can recruit good units. It is time to turn inwards and towards Babylon and Susa.

Here it gets tricky. The geography of the game is such that you have to pursue a certain path. The mountains of Persian/Iran are such that there is only one path thru, and you may encounter heavy resistance.

One good idea so Alexander is not killed is to send other troops and generals ahead at all times to deliver the initial blow, with Alexander behind. This isn't what happened historically, but other generals are effective, and the greek fighting units are superior to the Persians at all turns.

Thus, if a battle is lost, it is not a catastrophe--rather, you come again with Alexander, and he finishes off the depleted forces.

This process can take some time, but you have 100 turns to conquer Persia.

Once you finish the task, there is a nice little graphic celebrating you as the conqueror of the world.

At this point you should cry and be sad, for like Alexander, you have no more worlds to conquer.
