Getting 100% was quite fun, satisfying.

approximate amount of time to 100%: 100-200h
Estimated achievement difficulty: 8/10
Minimum number of playthroughs needed: 1
Multiplayer achievements: No. (but you can get achievements in multiplayer)
Missable achievements: No.
Grinding Achievements: Yes. Both production/minute and total production of certain parts... 20M green circuits being the worst.
DLC-Only achievements: No.
Time-gated achievements: No.
Speed-run achievements: Yes, Launch rocket in 8h most notable
RNG-achievements: No.
Does difficulty affect achievements: No (you can make a super-easy map).
Unobtainable/glitched achievements: No.

The game is the progenitor of a genre of games. It's simply awesome to this day.
Achievements are overall dependent on having an efficient factory but can be "cheesed" by making a flat map with no polution and semi-peacefull biters (the options that disable achievements are clearly labeled)

The internet is full of guides and videos. And you can even import and auto-build entrie bases... they can get most of the achievements for you

The game has an internal achievement tracker and I want to say that's simply really good QOL.

Lastly i'll note about 2 subjects that came up with this game:
* The developers tend to get into politics ... taking sides on social issues. I find it quite annoying to be preached at by my escapism ~NO MATTER IF I AGREE WITH THEM OR NOT~ .
* The price is fixed and doesn't ever go on sale ( from 5E to 40E depends on where you live on the globe but averages to 30Euro/$). And while I agree with the devs that sales usually ensure you buy games that are never played due to FOMO I must say that the game (in my opinion) might not be "worth all the money". And that's something that sales do help with... for some players this games is worth 60$ and for some it may be worth 15$... and with this I feel that choice is now removed from the player.

Edit: 400~ hours in ..game's still fun. Mod support is done through the game itself... The community is creative. Can't wait for the Expansion.
