Oolite
Oolite is a space sim game, originally written for Mac OS X in Objective C using Cocoa and OpenGL. Stable ports for *NIX exist, a Windows version is in late Alpha stage.
It was written by Giles Williams as response to the withdrawal of Elite - The New Kind from the internet. Although inspired by the work of Christian Pinder, following David Braben and Ian Bell, the work is an independent interpretation and expansion of the original game.
Oolite is designed as a small game that is easy for users to pick up and expand upon. Almost every aspect of the game can be modified using simple, free graphics packages and text-editors.
The game and source-code are offered for free under a Creative Commons License. One of Giles' priorities for development was to separate the game engine from the game materials (graphics, models, AI, text-strings etc.)
