Today is the launch of the LuaGame site. This will eventually be the source for information about LuaGame, a game programming environment that is currently in an alpha/beta state. It is somewhere in scope between PyGame and GameMaker. However, unlike PyGame, LuaGame is not a library. It is an execution environment. What this means, is that the game code and data is all stored in its own directory, and the luagame executable is run in the data directory or passed the directory on the command line. Also unlike PyGame, LuaGame does not merely expose SDL functionality (LuaGame is built on the SDL libraries), it wraps it in higher-level classes and functions. LuaGame also does not have a graphical IDE like GameMaker.
Unfortunately, there is no public repository at this time, and the initial development release isn't coming for a few weeks. In the meantime, a logo and perhaps a site design are needed.
