**April Grand Strategy Month**

April is officially **Grand Strategy Month**!

The whole month is dedicated to the greatest macro strategy games, empires, diplomacy, geopolitics, grand decisions and systems that actually matter.

Welcome to the **Grand Strategy Jam**  -  your chance to build the next big thing in the genre we all love.

---

**Grand Strategy Jam** is an event dedicated to designing grand strategy games on a macro scale.

We don’t expect huge amounts of content or polished graphics. Focus on creating **systems** where the player makes decisions at the level of a nation, empire, or global faction. Smaller, playable prototypes are very welcome if they capture the depth of the mechanics well.

**Jam Goal**  

Create a game built around grand strategy principles.  

Your project should put strong emphasis on **at least one** of the following:

- Territory management on a global map (macro management)

- Complex diplomacy and relations between independent factions

- Dynamic geopolitics and fluidly changing borders

- Macroeconomic simulation and long-term technology development

- Wars and conflicts resolved at the strategic level (no unit micro-management)

**Rules**

- New projects are recommended, but developing an existing project is also allowed.

- Any engine and programming language is fine.

- Teams and solo creators are welcome.

- Pre-made assets (free or purchased) are allowed if you have the proper license.

- Use of AI tools is permitted, but **must be clearly stated** in the project description.

- The submitted project must be playable.

**Rating / Feedback Criteria**

Even though there are no official prizes, here’s what makes a great Grand Strategy Jam entry:

- **Strategic Depth**  

  Decisions feel meaningful and have real long-term consequences.

- **Grand Strategy Focus** ← Primary focus of the jam  

  The game clearly emphasizes at least one core pillar: macro territory management, complex diplomacy, dynamic geopolitics, macroeconomy & tech, or strategic-level warfare.

- **System Interaction & Emergence**  

  Different systems (economy, diplomacy, map, tech…) interact in interesting ways and create cool emergent moments.

- **Clarity & Playability**  

  The prototype is understandable and fun to play even if it’s small.

- **Ambition vs. Execution**  

  Smart scope and good delivery within the jam time limit.

**How to submit your project**

1. Make your game during the jam.

2. Publish it on itch.io.
