I voted +101 hours !
I'm totally sure I spend +120 hours to become a L45 hero (FoV ending) ... !
But it was worth my time ...
Okay, I always take my time and each new level I now do my TTTTT : a Trading Tour of the Ten Thousand Traders
I remember starting the game, do the TTTTT I was busy for 1 hour playtime checking all the merchants inventories ! That was long, I know, but I was "learning" how to travel & teleporting the best way to make a TTTCTTT, or : Travel Teleporting Trading Circle of the Then Thousand Traders

But at least I spend many hours (minimum 20 min each level X 45 = 15 hour) doing my TNT (Trading Navigation Tour) during a whole playthrough
