I’m 140 hours in and have yet lots of side quests and story missions to beat. I like to go slowly and role play in these RPGs, so i can see myself playing for 100 extra hours.
That said, i think that the game is not prepared for people like me who wants to keep playing. After 60 or so hours, the game turned too easy. Money is too easy to get, good stuff is not expensive enough, bandits are too easy to kill, etc.
