The better question would be, ‘What can’t you do?’ Without installing a single mod, I had the time of my life. Being an RPG sandbox medieval title, ‘what exactly is there to do’ just isn’t the right question.
Again, the number of hours put into this game by the average player are astronomical compared to other games, easily reaching the 500+ hour mark for a decent majority.
The primary draw of the game is the single player experience.
