Medieval Dynasty is all about survival, growing knowledge and power, and ultimately creating your own town and having a family to leave it after you die too. To do all of this you will need money. At the start of the game, it can be difficult to figure out how to make money, but there is a simple and effortless way to sink coins.
The important thing to remember is that even if the money for you is limited, your neighbors are rolling in the dough, so the best way to make money early is to sell them items. In the nearby town you will find many traders who are happy to buy items from you, and there are two items in particular that are good for sale. The Humble Stone Ax and Stone Skinning Knife are easy to craft and will sell for 28 coins and 21 coins respectively.
You can craft the stone ax with 10 sticks and 2 stones, while the stone skinning knife will take 6 sticks and 2 stones to make. Sticks and rocks can be found quite easily on the ground, and you'll come across a lot of them while taking on other tasks. Crafting the Stone Ax and Stone Skinning Knife can be done in the Crafting menu by holding down Q, then just head to the local tavern and sell them to the merchant there for gold.
It is also important to limit your expenses at the start of the game. You can get water from the river, and food can be collected from the ground as mushrooms or by hunting deer. You should save your money for items which are very hard to obtain and only take out your coins when you are struggling to progress in the game. If you just sell a stone ax and skinning knife every day, you will accumulate quickly. a sum of coins to help you later in the game.
