That's an interesting way to look at it. I know the Minecraft era definitely had its equivalent code-related fanbase who'd make plugins and mods in Java. The age of Minecraft has also faded away though (besides the most recent Pewdiepie revival) and I'm not sure Fortnite or the other shooter games of today have a programmatic side.
With Minecraft, even just watching a Youtube video and copying their build-style to make something cool is enough for a kid to learn that they can be a creator.
They realize that there's no magic; all it takes to make something nice is a little knowledge, and a lot of work.
From what I've seen of Fortnite, it promotes a different kind of creativity, which is more like creative problem solving (boxing people in, riding rockets, etc.) But it does have a sandbox mode that I've seen some interesting creations from.
Fortnite defintely doesn't AFAIK, and their nature as a multiplayer game invites competition, and therefore, cheating making it important for the developer to actually de incentivize modding. I am very disappointed that modding of famous games is going down honestly.
