My 13 year old is motivated and pretty good at basic scripting stuff.

He thought it was cool that Stardew Valley was made all by one guy (music, graphics and code). He wants to try to make his own game.

What courses should I set him up with?
What tools does he need? Stuff like Sublime Text?

He thinks he wants blender and unity. I’m in marketing. I don’t know where to send him and he’s way smarter than me.
