Game description

Game Objectives:

​

Set upon a green field with a river running through it, the player must choose which buildings to construct and where. Each building costs resources and can take multiple turns to build. With only 100 months until Forkbeard calls upon your army, every choice must be calculated to ensure enough fully equipped soldiers are ready. ��Some buildings collect raw materials while others craft weapons and boats from those raw materials. Some buildings produce more when they’re near other buildings of a particular type. Builders can be added to enable more concurrent construction projects.

​

Every resource used to increase resource production are resources not being used to create soldiers.

Game mechanics

• Turn System: The player will be able to begin a new turn 100 times. Each turn advances building construction, raw resource generation, item crafting, and soldier training. There is also a chance of a random event occurring on each turn.

​

• Building: A panel of building options are shown to the player which they can drag and place buildings onto the game field to begin construction. Each building will consume and produce relevant resources. Buildings cannot be placed on top of each other.

​

• Army Building: In the river, boats will be added for each one the shipwright makes. As soldiers are trained, they are placed in the boats. As the weapons are made, they are given to the soldiers. Once the river is full of boats full of armed soldiers. Then the player has basically won the game. The river acts as a progress bar in a sense.

​

• Random Events: After each turn, there is a chance of a random event occurring. Every random event will have some effect on the village and present two choices to the player which have random chances of making things worse or better.

​

​

Game mechanics

• War Strength: The war strength of the player’s village is calculated as the number of full boats. If this is above a certain threshold on turn 100, the player wins.

​

• Information System: When the player hovers over buildings, a menu will show all the relevant information to help guide the player’s decision making process. Announcements are shown in the center of the screen.

​

• Effects: Effects can be placed on the village which last a certain number of turns and affect the production of some resources in either a positive or negative way. Active effects and their durations are shown in-game

​

• Disabling Buildings: The player can disable or enable certain buildings to help prioritize shared resources.
