How about broadening “Code Snippets”, instead calling it “Marketplace” and dedicating it to all assets and code snippets that are ready to copy-paste into one’s game (ie. a poor man’s asset store), and then introducing a new “Tutorials” or “Help Materials” section for all samples and tutorials? This would set a slightly clearer division and also give non-code assets that people want to share a good home.
I’m still a little iffy on the overlap, though. For example, it feels like this might go into Help Materials since it’s a sample program, but at the same time it’s also a bunch of scripts/shaders people could copy-paste into their own game, so from that perspective it seems like it would go into Marketplace.
