Right. I meant a specific very prescriptive guide for the kids.
If they're 14+ Unity is realistic and is the same thing the pros use.
I haven't tried Unreal Engine for Fortnite but if they play it, it is probably the best option.
Minecraft, Bloons and Terraria modding is also pretty good.
You can give them a GPT4 sub and it seems to do a good job answering basic computing questions if this is going to be their first time e.g. installing a professional tool.
They are already making scratch games. Would be amazingly fun for them to run a game on the deck just like any other game. Not in a browser, which is how most of those games are executed.
I'm guessing the lack of guides for this specific thing is because it's trivial to do.
I could also dream of a path to live coding on the deck. Would be great to have a debugger hooked up for developers.
