Yeah. Unofficial ILs sound like a better idea. You could link a document to resources that people can edit themselves? You could even add a link to your video for it easy enough. Sunshine has the same sorta thing actually. Have a look in Sunshine resources. I have a personal spreadsheet that I use to compare my gold splits to others to see where I can improve my times. Perhaps a spreadsheet where we can all put our gold splits would be good too?

Sunshine had a spreadsheet with guide videos for each star in the any% route with beginner/intermediate/expert starts. Maybe something like that would be better for encouraging new runners? I think having ILs isn't really as viable with Galaxy like they are in 64 and Sunshine coz in a normal run you can't skip cutscenes and they can sometimes/most times affect the patterns in the levels which makes them not as beneficial for people learning.
