You can't code but can you do content or concept art? If so you have a better chance of making a team to get a project done. You are saying you have a design right?... look into game design documents.

You could try Game Maker - a visual drag-and-drop based program. ... but it is good for beginners imo.

I 4th this suggestion. VERY STRONGLY.

Game Maker will eventually limit him. Perhaps it's best that he learns some Python or Java (Or both!) at Code Academy and moves to Unity? Unity is much more powerful and flexible, and he can later move onto things like Monogame if he wants more control/customized tools.

If you do get into Unity, OP, don't use Boo or JavaScript. There's not many resources for them, and they are not very useful either (As they are customized to Unity, and won't match their "real" counterparts).

You can make a full game in Unreal Engine with all the needed logic and interactions using Blueprints. Blueprints is a great way to program for people who don't want to code. Go ahead and watch a few videos and see if it seems doable to you.

I second this, but it's still coding.

Just because youre dragging and dropping boxes into a flow chart and connecting them with lines, it doesn't mean it's not coding, it's just visual scripting.

You will still need to understand the maths concepts behind software, such as variables, arrays, loops and conditional branches, otherwise you will just fail to grasp the concept.

The very first time i tried to write a program in basic for example, when i was 12, i couldnt grasp the idea of "A = A + 1" and kept thinking i had to have a new variable each time, because in my mind "A = A + 1" didn't balance as algebra and made no sense due to the way it was taught in school.

As soon as i got used to the idea of variables being 'black boxes' for data storage (this is a great way for a newbie to grasp the concept by the way) it all made sense.

I suggest if you do want to create a game you learn the basics of programming even if you dont want to program. You'll need to communicate with programmers so it's best to speak a bit of their language, "pidgin-programmer" if you will. Lean the basics of flow charts, program flow, and loops, and you'll at least be able to express your ideas in a simple unambiguous way that a programmer will understand.

Good luck!

Eventually. But not right now. And not for a long time. I'm not against learning to program. But if the point is to make games and learn some programming skills/knowledge, then Game Maker meets both criteria.
