Fabula is a Python game engine suitable for adventure, role-playing, and strategy games and digital interactive storytelling. It offers a client-server architecture, an event-based protocol, multiplayer and networking capabilities, a multi-threaded server, an abstract, visualization-agnostic model of a game world, an asset manager, and a plugin system. Gameplay can be recorded and played back. The code is well documented and runs on Linux and MS Windows (it should work on OS X, too, but this has not yet been tested). Fabula can be used as a library to develop your own games. As an alternative, you can use the included Pygame-based graphical editor and the default game engine.
