Start the game:
When you start a new game, you will can choose a place to build your town center. This is also an excellent moment to observe the map and locate resources. You may not find a perfect place to get all resources near your tc, it's fine, remember their locations before you place your tc and you can expand toward them.

Necessary resources:
Animals(preferably deer)
Water(press i to see)
lots of wood and stone

High priority resources:
Herbs, other food sources, clay and iron ore.

Then you can start your game, try whatever you want but here are some tips for early game:
1.Villagers can be micro directly, you can manually control hunters to kill predators or gather a wolf exterminating squad.
2.Hunters also act as militia, their bows are excellent against unarmored enemies.
3.Don't over produce foods which just rot in your warehouse.
4.You can cancel food storage in your storehouse so all food goes to cellars.
5.Better prepare your field before planting crops, if you need food just plant beans which fertilize your field.
6.Farmers and foragers do nothing during the winter, you can use them as laborers but remember to change it back in the new year.

Hopefully you make your way to tier 2, the age of trading. Trade is the most powerful(and broken) mechanism in tier 2. Trade allows you to acquire tier 3 and exclusive resources and livestocks to begin proper farming. Heavy tools and cows are only available to you by trading at first, you can produce them later. Heavy weapons, crude weapons and platemail armors can only be acquired by trade.

The broken part: 2(later 3) merchants can trade with you at the same time. However, one may sell something the others want to buy at a lower price. Then you can get as much as 100% tariff for nothing, so always build a trading post even if you don't need to buy or sell anything.

Defense strategy:
You can build a wall to protect your village, but walls are quite expensive and don't really stop raiders for a long time. What I recommend is to place all storage building close to your tc and trading post, especially your vault. After that, place lookout towers to create a kill zone for whoever has the courage to touch your gold. You don't have to permanently man those lookout towers, only need them when the attack comes. You can also place your barrack nearby.

That is the end of my tips,and here comes my ideas.
1.Make a bottom to summon all armed personnel including hunters to defend the village.
2.Stop villagers eating the glass jar when they have their preserves.
3.I don't understand why villagers can't make crude weapons, sharpening a stick as a spear seem to be more sensible than fighting with fists.
4.Fallen raiders just vaporize, they don't leave anything even their bodies.
5.Bear carcasses should count as boar carcasses really.
6.Free the farmers and foragers during the winter as laborers.
7.I hope there will be horses in the future so I can make a real mounted knight in my village.
