Off to a good start if he has planned some of the game on paper. I would try and get him to do the following: 1. Take his notes and make a basic game design doc. If its 3d, focus more on what the main character can do than anything else. 2. From the design doc, see if theres any free or free adjacent unity plugins to do what he wants. 2a. If he tries out a feature and he doesnt like it, send him back to the design doc, seeing as thats what he sees his role as. 3. Make yourself more of a systems integrator. You will probably need to learn some stuff, like blender scene importing, and basic game logic. But its pretty easy these days to knock something at least fun to demo together from the unity store.
