Ok the first 10-15 days of minecraft you will see retarted cavemen running around and natural structures,
The next 5-10 days you see That man is starting to live in caves, create little fires for warmth, living with other cavemen, developing wooden weapons, and eating raw food.
The next 15 days you see that they have started to eat cooked food, build small structures, create villages, and use stone weapons.
The next 10 days they have bigger structures and villages turn into towns.
The next 30 days they have developed wooden walls with soldiers to protect the town, a single king rules the town. (may be aggressive or passive, aggressive have better castles and soldiers, you may live in a passive town)
The next 12 days they use cobblestone walls and discover iron weapons and armor.
The next 5 days they start to build up an army and conquer other lands
Then finally, you can build a city, create an army, a wall, and go to war with those enemies!
