It looks neat for a teenager, I'm definitely impressed at the "all-in-one" idea that it has DCC DAW and game engine together. But the sculpting is clearly pretty rudimentary. One video I saw, a guy had sculpted Kermit and it looked great; but he complained that it took a massive amount of time. In Blender, it would be an afternoon project.

Once you understand what's happening under the hood and you know your hotkeys, you can really fly around and do stuff fast.
