Biggest problem with the non-tutorial is...

[brunzenstein]

... a new user must find it first.
And thats not an easy task as one has:

1.) to know that such a beast exists in first place
2.) find it buried in the initial setups

instead:

there should / must be a splash screen for a newbie announcing:
"Her you are invited tu jump right into ice-cold water to find out what's it about Factorio...!"
or something similar leading right to the "appetiser"

Agreed. The main menu is one of the GUIs that has yet to be reworked, but don't worry, it's on the todo list
