If any game can be called addictive, it's Factorio. Now we have impressive reasons for such a title.
A Reddit user shared his friend's Factorio statistics. He played the factory-building simulator for over 47,000 hours. Even with such an impressive result, the player was unable to unlock all the achievements, and 4 achievements remained uncompleted.
The author explained that not all 47,000 hours are active play. A lot of the time, the game was just launched on PC and then shut down. In addition, some of the achievements in Factorio are so difficult that they can be completed even in 100 thousand hours. For example, for one of the achievements you need to complete the game in no more than 8 hours, or for another you need to produce 20 million electrical circuits, which is actually as ambitious a task as it sounds.
