Unity 2.5

Unity is a multiplatform game development tool, designed from the start to ease creation. A fully integrated professional application, Unity just happens to contain the most powerful engine this side of a million dollars.

      Integrated Editor: “Everything is done through Unity's simple user interface. Thousands of hours of thought and spit-polish have gone into it.”
      This is probably one of the best features of Unity. While the editor does not do everything, it does combine external editors for scripting, textures, and model editing very cleanly. It allow you to easily sort all of your assets and files in one place, acting as one of the most organizable interfaces I've ever seen.

      Graphical Power: “Unity has a highly optimized graphics pipeline for both DirectX and OpenGL.”
      And uses them well. I was able to have very high resolution meshes (such as poser 5 models) on the screen without significant framerate drop. It's a very professional engine, and does run on multiple computer configurations. It seems capable of turning off and on features and the computer can handle them, even in the web player.

      Asset Importing: “All major file formats are supported, and almost any art application can be used with Unity.”
      To point out how easy it is to import assets: I dropped a model that was boned and animated into the asset folder of my Unity project, and it converted it in mere seconds. I then dropped it into my scene, and with a single script consisting of just a half dozen lines of code, got it to loop the animation and move around the scene. There was no special modifications. No checking Z rotations. No checking the rotation of bone sets to make sure they did not crumple up my model like a paper in the wastebasket. It just worked.
      I was able to adjust the size of the model for the scene with a single modifier that worked for the model AND the skeleton.
      Textures, including such “oddities” as TGA, imported fine.
      Scripts are text files, and edited in Scite in the windows version of Unity 3D. You can redirect it to other editors if you are so inclined.
