Sorry if this has been answered already but how many hours does it take to finish the game?
It's very hard to say as it depends entirely on your playstyle. If you play a fighter and get into every fight, it might take a while considering that most fights would require several attempts. If you play as a non-combat character, then it will depend on your reading speed. If you play a hybrid, it might take you even longer because the fights will be much harder.
According to Steam, it took me 7 hours to do the 3 starting areas (Teron, the mine, and the raiders' camp) with a pure fighter, but I was alt-tabbing to take notes (I was testing difficulty and block), so it's hard to say.
Quite a few people on Steam played the early access version for 40-60 hours, but I assume that it includes 2-3 playthroughs with different characters.
