Be prepared to fill some early and large requests for manufactured goods. Mine some copper and make some weapons as soon as you can. Not only will you need to dispatch weapons to other cities and send off troops to distant battles, but you will also need to defend the city from invasions. Make sure that you have some transport ships and warships for dispatching troops via ship and defending against sea-borne attacks. Invasions could come from any direction.
Troops are also handy for ridding the area of hyenas.
Keep in mind that you will need to import sandstone for Mausoleum construction, and provide bricks and limestone for the Brick-core Pyramid. Prove to your people that you are worthy of the title Pharaoh.
