'better' for what purpose?
More or less game development...
Oh ok, it is nice to see the effort being put in by greenhouse. Never knew they were doing that. But are they planning on releasing an official 3D greenfoot? I know you can use jmonkey if you are actually going into the 3D stuff. But if you want something that is more of a teaching tool(which greenfoot is supposed to be (I realize that I forgot to mention that, sorry)) for 3D game development, wouldn't a 3D greenfoot be better?
