I have completed all the achievements; I have a single colony that has all the achievement minus the cumulative ones and planetoid specific ones. I play on survival, though also on Spaced Out planetoids (so that probably makes its a bit easier).
And I am impressed and flabbergasted at the quality and complexity of the systems people make. I cannot overstate how very ad-hoc and jerry-rigged my bases are in comparison to the beautiful systems I see on this sub.
And then underneath the picture of something I can barely understand and would be hopeless to replicate - the OP says something like "Can't figure out how to get to end-game, or launch a rocket, or etc. etc."
I presume it's not a broad trend and something anecdotal I just noticed and I find it neat that maybe there are a number of skillsets required to fully play the game but don't actually overlap.
TL;DR This game is awesome and you guys are impressive.
Sidenote: Any oldheads remember "Robot Odyssey"?
