Unknown Horizons is an open-source 2D isometric real-time strategy simulation game focused on economy and city building, written in Python. Players expand a small settlement into a wealthy colony, managing resources, taxes, trade, and diplomacy with other settlers.

Use cases

• play an open-source Anno-like city building game
• run a real-time economy simulation on Linux
• contribute to a Python game codebase
• host or join multiplayer strategy matches
• study component-based game architecture with YAML data files
• find a starter-friendly open source game project to hack on

When to choose

• you want a free, open-source city-building RTS with economy depth
• you want to develop or mod a Python-based game
• you need a cross-platform strategy game that runs on Linux, Windows, and macOS

When to avoid

• you need modern 3D graphics or a polished commercial experience
• you want a game with an active large development pace, as the project is in maintenance with a Godot port in progress
• you need a game without external engine dependencies like fifengine
