pre to nano ( space ) pocket   copper

as soon as you get copper have cits start making a wall, 8 - 12 cits, and begin making farms, always start building
around your capitol, make 5-6 farms and populate them before filling gold and iron mines

if you have reached pop and still have a large army that is not needed at the moment, place the army in a fortress
and make more cits so you can make more farms, 8 total, and populate your iron and gold mines into capitols, you may 
also need to help your wing with making copper, he may need food because of heavy attacking

as soon as you can, advance to bronze
