It's lakes and mountains for me, but absolutely yes. I've been looking forward to that since the Kickstarter, and arguably in my headcanon since 1984 when I read
The Dark Wheel and its mention of retirement beside an alien sea. You could
sort of do this in
Frontier and
FFE but the graphics, while impressive for their day, weren't as impressive as the imagination when it came to planet surfaces.
I've waxed lyrical about this on a few threads over the years but
this is among the earliest still available that I could find.
(Aside: I just noticed that the penultimate paragraph in that post seems to predict the mechanics of synthesis using gathered materials, and even touch on the fringes of Engineering, several months before Horizons introduced them. I should have sent FD an invoice.)
