OpenSAGE is a free, open-source re-implementation of the SAGE 3D real-time strategy engine used in Command & Conquer: Generals and other EA Pacific RTS titles, written in C#. It can already load and render many original game assets and maps, but full gameplay is still under development.

Use cases

• play command and conquer generals without the original engine
• load and parse SAGE game asset files like .map and .w3d
• build a custom RTS game on an open-source engine
• study how the SAGE engine renders 3D models and maps
• reverse-engineer EA Pacific game data formats
• run Generals Zero Hour on Linux or macOS

When to choose

• you want an open-source, cross-platform reimplementation of the SAGE engine
• you need to parse or inspect assets from C&C Generals or similar SAGE games
• you want to contribute to or learn from an engine reimplementation project

When to avoid

• you need a fully playable RTS game today - gameplay is incomplete
• you need network multiplayer or AI opponents - not yet implemented
• you want a general-purpose game engine for new projects - it targets SAGE games specifically
