A downloadable game for Windows and macOS

Nasty, Brutish, and Long is a novel civilization-building game, featuring exploration, combat, and development. Compared to other civilization-building games, it's more intellectual, more open-ended, and tougher. Simple survival is a challenge. It has a focus upon deep, strategically or thematically interestingly mechanics over fancy graphics.

This is a demo that only includes the most important ~half of the ancient era. It’s fully playable, but lacks many features I hope to add later. The demo currently runs on mac and windows. It supports singleplayer and local multiplayer (2-6 players) automatically. Online multiplayer (over the internet; only 2 players) requires a few minutes of effort on your end. Game design is 100% human. Most of the code is AI-generated, mostly by Gemini-2.5-Pro-6-5.

Install instructions

Download the zip for mac or windows, unzip it, then run the executable. You might have to authorize it to run (the same way as any app downloaded from the internet).

If you have issues with the window being too big, toggle it to the small size, then close and reopen it. To play online multiplayer, install zerotier or similar and get the host's IP.
