I'm totally losing sleep playing this game. It's so immersive. It's everything I expected and more. Like one guy said in a a recent Fallout 4 forum post "I bought the game expecting to roam the Wasteland killing raiders but instead I'm trying to decide what color living room furniture I should outfit my settlement base with, like it was The Sims: Post-Nuclear Apocalypse version." So true.
Here though, I'm not bothering with base building, I'm out bravely exploring the dangerous environs. And soon after I enter this building, I wonder why I just didn't stay in Sanctuary that morning.
