Comment Unity 3D proves it is (Score 0) 165
Check out Unity 3D, a multi-platform 3D IDE focused on letting you use 1 of 3 languages (Javascript, C# or a Python variant) to do all the scripting of your game objects. It's extremely awesome and fun work and I've seen some great games created with it. It makes it all the better that they can run on Mac and Windows, on the desktop or via the browser. Sad for Linux folks who can't play their games yet though.
