[KCD2] How long is this game?

How long is this game? According to the in-game statistics I have played for 62 hours. It took me around 40 hours to reach the second area, I am currently gathering the band for dry devil and done a lot of side quests in kuttenberg already. I’ve mainly explored the city so far, today I found Sigismund’s camp, and I realised there are so many things to discover. There are lots of quests I havent even started yet. Im just wondering how long is this game? Im not complaining, just curious. I even want to go back to the Trosky region. I’ve read some posts where people said that they finished the game in like 40-50 hours. Like how?
