So, I never really gave this game a chance the last time I bought it, but I'm giving it a try again. I was wondering how many hours I'm looking at, when doing all side quests incl. dlc? I'm hoping a 100 hours or more.
I did every main, side, and unmarked quest and discovered every location. I used the wiki to help find notable loot at each location. Take the explorer perk to help get to all the locations. I started it a year and a half ago and just finished last night. With all the dlc's and the original game, I put 275 hrs into it. I am obviously a scavenger, explorer, and completionist, but you can easily get 100 hrs out of it.
