My usual build at the start of the world.
I. Resources
~Build mines to level 15. Don't go higher since that would be mine whoring.
II. Troops
~Build Barracks and upgrade it to level 10
~Build about 500 Spears for farming
~Farm 5x5 constantly. If your neighbors have walls and swords and stuff, build more spears to attack them with.
III. Catapults and Rams
~Don't build these as they are cumbersome and they will only serve to slow down your army.
IV. Resources
~Grow mines to level 30. Anything below it will be sub par.
~Make sure to maintain 500 Spears. Getting more will overpopulate your village and will force you to upgrade the pesky time consuming farm which you don't need.
V. Nobles
~I usually don't reach this stage so i'm not sure.
~I think it would be best to build a noble, and noble the closest village to yours to make sure that your villagers can have friendly interaction with the village you just captured. This will make you and your villagers happy and they will give you an awesome secret gift if you do.
VI. Advanced
~Press "Up, Down, Right, A, B, A, B, Up, Up, Left, Right, then A" before sending every attack. This makes your luck +25% everytime you attack.
Hope my start up was of use. ^^
