How long does it take to 100% the game?

[Sunbach]

I am looking for a game with a long playtime. For reference I 100% SV in about 200 hours years ago and SV since then has had many content updates.

Is there much content in this game?

I completed it in like 200 hours, which seems to also be the median on steam hunters.
Though if you want to complete everything in the game, not just achievements, it will take a bit more time

I'm a bit over 300 hours in and almost complete. I think it will take me about 10 or 20 hours more, depending on if I didn't forget something again.
