There are video games out there that pose challenges very similar to the one's one encounters when programming. Several commenters have mentioned in other threads that Factorio is such a game. (I never played it myself.) If that's the kind of game your brother is interested in, you might sell him on programming by saying: "In essence, it's just that, but paid."

I remember playing an educational web game long ago where you had to program a robot with a limited set of control flow statements so that it could autonomously reach a goal. The game had an isometric perspective and the robot had to react to all kinds of obstacles. If anyone remembers this game, please post a link. It was great but I didn't bookmark it.
