I wonder if there's a way to smooth out the transition into modding "real" games that teenagers are already playing with their friends. I'll bet it would be pretty motivating to have that kind of power in these online spaces where a bunch of your friends hang out.

Minecraft and Roblox support mods written in Java and Lua respectively but it's a pretty big leap from Scratch to Minecraft mods.

I was recently discovered a dedicated editor for Minecraft modding (https://bridge-core.app) and that seems pretty cool. A lot more could be done in this space though.
