About as close to rocket science as MineCraft gets ...

Narcogen and Blackstar make parts and attempt to build moon rockets by using a "NASA workbench".

I'm glad KSP doesn't require us to wave swords at parts in the VAB or peel potatoes.

Meh.

100% crafting, 0% rockets.

Galacticraft is a great concept! Indeed, I hope they will make flying in space more interesting  given the way Space Stations and other worlds are handled as separate dimensions, it could have something like Starbound's planned space combat system, kinda?

I use it myself, and boy, it takes a lot- I like it!
