EDEn (the Exodus Draconis Engine) is a free and open-source engine used to create top-down, 2D RPGs with 3D effects. Aside from the usual trimmings one would expect from the genre, the engine aims to also enable some gameplay elements typically found in adventure games.
The initial purpose of this engine was to facilitate the creation of a very specific game (Exodus Draconis, for which the engine is named). While development of the game continues, the engine will contain common code and utilities created along the way that may aid in the development of other RPGs.
EDEn is programmed in C++ and uses SDL for graphics and audio. By exposing C++ functionality as a Lua API, EDEn allows game developers to develop and tweak gameplay, quests and stories on the fly without requiring the source to be recompiled. The engine can also handle a variety of image and audio assets supported by SDL_image and SDL_mixer, respectively.
In general, EDEn aims to help game designers quickly turn RPG stories, gameplay and level designs into playable RPGs.

EDEn makes use of the CMake build system.
EDEn depends on the following development libraries to build the source:
Windows developers will also need the Windows implementation of dirent.h.
EDEn requires the equivalent runtime libraries to execute.
Maps and tilesets in EDEn are created using the Tiled Map Editor (http://www.mapeditor.org). For more information on the Tiled Map (TMX) and Tileset (TSX) formats, please refer to the Tiled wiki (http://github.com/bjorn/tiled/wiki/TMX-Map-Format).
To build EDEn by command-line, navigate to the root directory and run the following commands:
cmake .
make
./edenOn Windows, CMake can be used to create a Visual Studio solution that can be used to build and run the source.
On Mac OS X, CMake can be used to create an XCode project that can be used to build and run the source.
