Put both workers on production.
Turn 1: Rush a Warrior
Turn 3: 2nd Warrior should be able to be rushed.
Start exploring away from you directly. Your goal here is to get to one of the other civs before they have any defenses.
You can cheat a bit if you want and save the game right away, run your guys around and map out the other civs locations.
Anyway, rush to grab a civ, the closest one first. Try to take out England early if you can, Greece before they get any defenses up helps a lot too.
Grab huts after you get your easy one or two civs, you should get three times your share of huts. Huts will give you gold, galley, or horseman, all of which are very useful to continue. You should be able to take your second or third civ out with a horseman army fairly quickly.
When I did it, I was only able to get one civ before the defenses went up, so I actually left the next closest to me alive, hopped on a galley and took the other two quickly with horsemen armies and a heavily advanced warrior army.
The next closest was left around because I was able to start sending my newer troops to it while the 2nd to last city was being wrapped up.
I think I finished by 50 or 70 AD, lots of extra breathing room. Only thing that gave me any trouble was running into a archer army in one city, the numbers were close so I relied on save and load to get through it, I had eough extra time I could have brought another army over though.
