While I don't think this is quite as polished as Scrivened's Hyperlanes book, I still think that this is a really compelling 5e supplemental. By building off of D&D 5e's rules, it allows you to play using rules that you already know while still bringing something new to the table. I'll be using this to create a Fantasy-Western setting.

Some of the best and most detailed homebrew I've come across. I've followed this guy on reddit for a little while now (coolgamertagbro) and his content is always top notch. He always responds to critique and he always answers questions.
