jMonkeyEngine is a game development suite made especially for game developers who want to create 3D games with modern technology standards. The software is programmed entirely in Java, intended for wide accessibility and quick deployment.
Working with this engine needs some experience of game development.maybe a visual editor make it more more better( it has one in 3.1 alpha version). But I love this engine as the only true java 3d game engine.one good point is that Exporting for windows and android platforms is really easy. I hope it grows faster.
