Our "top game" was in moderation build on Steam for 18 days (!) and yet it was released https://store.steampowered.com/app/2389240.
The game did not pass the automatic Steam check and then began a very painful and long moderation. Steam tech support dug into literally every decal in the game and checked literally every inch of the game!
Bottom line: I had to cut out some content and delete 5 achievements.
