Screeps: World is a sandbox strategy game for programmers from Screeps, LLC. The name stands for "scripting creeps": instead of clicking on units, you write JavaScript that controls them. It entered Steam Early Access in June 2016 after a crowdfunding campaign and reached full release that November.
All colonies share one persistent world, and your scripts run around the clock, even while you are offline. Units harvest, build, haul, manufacture, trade and seize neighbouring rooms exactly as coded. WebAssembly also allows C/C++, Rust, Go, C# and more. The game is open source, you can self-host, and the official server runs seasonal worlds.
It is for people who enjoy programming for its own sake. It is paid, the base licence caps you at 20 CPU, and full CPU on the official server costs extra. No Russian language.
