StendhalDesign

This small doc tries to make a contract agreement about what is stendhal and what it needs to include. It considers the existing [Roadmap] and tries to give a coherent vision of what we are trying to get.

Consider using the Discussion tab to query about particular things or making suggestions.

Plot

Stendhal's plot is to grow pigs by taking them with you to eat on the plains or the forest.
The task is not simple because you will have to look after them because hungry wolves will try to eat your pig. So be careful and protect your pig.

Pigs must be bought when small at Farm, and sell later when you grow it at the Village. For each pig you sell when it has grow up, you will get an extra income.

You will need to spend money on getting new weapons and armors and healing potions.

As you see Stendhal is a minigame that try to push everything related to RPG:

• task
• actions
• areas

If Arianne get Stendhal working, the problem is just scaling up the result. :)

Design

Idea

The whole game area would looks like:

Players need to change zone in order to accomplish their task.
