Achievements with default settings

[teletubo]

I have finished the game like 4 times now, but never with default settings. I always tweak some things to make life easier for me.
However, I feel there should be the "ultimate" factorio experience, which is playing a game with default settings, and there should be a motivation for that. Currently I don't see any motivation for playing the default settings since it's just easier to decrease pollution, evolution, increase resources, etc.

Why not a simple achievement "Finish game with all default settings" ?
