Unity Game Development Tool now available Free

Unity - the 3D Game Development Tool that includes a simple visual editor is now available directly from the unity3D website . Have played with this briefly and looks really good. It is supports the importing of your Blender models, so is a viable alternative to using the Blender Game Engine. In fact with the Unity web player, and a license available for iphone develpment, it may just have the edge on the BGE ???
