The OpenBlox Game Engine is a free, open-source 3D game development kit written in Python.
Users create their worlds with Lego-like bricks, so no 3D modeling experience is required.
The engine is also cross-platform (across Windows, Linux, and Mac OSX, with iPhone and Android support being considered), and includes the following features:
* Scripting, via Lua * XML-based scene format * Cross-platform game distributing - write once, run anywhere * .zip game compression * A scene editor is also in the works

ReCaged is a Free Software, Futuristic, Racing Simulator.
With the main inspiration taken from the "RollCage" and "Rollcage: Stage II" games, it has been written from scratch with focus on high simulation realism and flexibility. It also supports highly detailed 3D models for both rendering and collision detection.
