We recently started a playthrough with Arig. I think we got a few cliffs too many:

We first had a regular playthrough with space age till the platform, then we added the mod, researched the planet, flew there, and landed. Cliffs everywhere.
Made it really challenging, but surprisingly, not impossible. We thought it was actually intended like this, so we kept playing. Got to the science pack even! Only then we checked how other players managed the scare space and saw that this maybe was not intended!
Mods active: Base, HighRails, Quality, SpaceAge, Planetaris: Arig (v 1.0.2), Auto Ghost Builder, PlanetsLib
(Maybe even keep that as a setting in the main menu, as a really hard mode)
