This page of The Witcher 3 Hearts of Stone guide offers an estimate how long it takes to complete the main storyline of the first expansion for Witcher 3, all side quests and time needed to unlock all trophies.
- The Witcher 3: Hearts of Stone is the first expansion set for The Witcher 3: Wild Hunt. As can easily be imagined, completing the expansion takes less time than completing the base game, but it still offers several hours of new content. To complete the storyline, you need to spend 15 hours.
- If we are in mood to complete all side quests, the game will take up 25 - 30 hours. This all depends on whether we want to explore all of the map, or only its smaller part.
- The players wishing to unlock all trophies will have to spend 40 hours in game. Considering that this is only an expansion, the playtime is quite massive.
- The Witcher 3 offers several difficulty levels that affect how quickly you are able to finish the entire game. Choosing the lowest difficulty level means that the enemies will be easy to handle, but higher difficulty level will make every fight a difficult one.
