Press kit

Everything you need to write about it.

Facts, copy you can paste, full-resolution images and footage. Nothing here needs to be asked for first — take what is useful and publish it.

Yes, you can monetise your video. The licence says so in as many words: advertising revenue, sponsorships, donations, tips and subscriptions on coverage of the game are all permitted, and so is monetised streaming. You do not need permission, a key, or a contract, and there is nothing to sign.

The same goes for the mods, maps, saves and videos you make with it — those are yours, and the licence does not claim them.

OpenDoctrines is a free grand strategy game in the mould of Hearts of Iron and Victoria: 1,641 provinces, six historical scenarios, and a country to run through industry, research, diplomacy, war and rebellion. It plays in a browser with nothing to install, and on Windows, macOS, Linux and Android.

Long — about 120 words

OpenDoctrines is a free grand strategy game built by one developer. It gives you a country on a 1,641-province world map and asks you to run it: the industry that pays for the army, the research that decides what the army is, the doctrines you commit to and then live with, and the neighbours, minorities and creditors who all want something.

Six historical scenarios ship with it, along with a map editor, multiplayer that needs no port forwarding, and a mod SDK that takes mods written in thirteen languages. It runs on Windows, macOS, Linux and Android, and — unusually for the genre — in a browser tab with no download and no account, which means it can be tried in about ten seconds.

Things worth knowing

Angles that are actually true, if you are looking for one.

A grand strategy game that runs in a browser tab. The genre normally means a multi-gigabyte download and an hour before you have done anything. This one starts in seconds, on a school Chromebook or a phone, with no account.
It plays inside a Discord voice channel. Launched as an Activity, everybody in the channel is in the same game, and the invite is a click.
Twenty-one languages, from a solo developer. Including Arabic and Urdu, which means right-to-left layout was done properly rather than skipped.
The AI is trained, not scripted, and its development is written up in public — several hundred journal entries recording what was tried, what was measured, and which hypotheses turned out to be wrong.
Mods are compiled, not interpreted scripts. The SDK takes Go, Rust, Zig, C and others, compiled to WebAssembly and run in a sandbox.
It is free in a way that has no second shoe. No advertising, no telemetry in the game, no cosmetics, no paid version waiting.

State of it

The game is an alpha and is labelled one everywhere. It is playable start to finish, has a tutorial, and people finish campaigns in it — but systems still change between versions, and saves do not always survive a version bump. If you are writing about it, that is the honest framing, and it is better for both of us than a review that discovers it later.

Permission, in plain words

Everything on this page may be reproduced for coverage of the game — articles, videos, streams, thumbnails, storefront listings and social posts — including where that coverage is monetised. You do not need to ask. Credit is welcome and not required. The only thing not permitted is presenting the game, or a modified copy of it, as a commercial product of your own; that is what the licence reserves, and it has nothing to do with writing about it.
