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
