This game is like crack.
I decided to finally retrieve the Soil Stradivarius from Vault 92, including the trek to Vault-Tec to discover its location. This turned into like a 4 hour escapade because of how I generally don't fast travel.
So here I am in the D.C. area, and I keep coming across ruins with Super Mutants or Raiders in them. Of course I have to clear that and loot everything! Then I get into the subways and I have to find every nook and cranny and see a little bit on the outside of each door, just to see what's up. Hey! More Raiders and Super Mutants!
Finally, I'm in the open Captial Wasteland again. I make a beeline for Vault 92, but whaddya know? Some hollow arrows just a little bit off center. Gotta see what's up with those! Found some big ass ruined building with some Deathclaws and they were kicking my ass so I backed off, but I went through all the other shit I found other than that.
Finally! Vault 92 at last! Then I discover the place is somewhat large, and I'm easily getting lost (I wish the game's map could handle multiple floors better). I must have spent an hour at least just in Vault 92. I can't find the fucking Stradivarius! You know that saying "It's always in the last place you look." Regardless of the fact that it's a ridiculous statement, it literally was in the last place I could possibly look. There was a section of the vault I hit early but apparently didn't fully cover. I missed one room. So I had gone through the entirety of the rest of the vault and then again a second time before I got to the very first place I went and found the turn I didn't make.
After retrieving the Stradivarius, I fast travel this time to the lady that wants it, give it to her, and exit the game. Shit! It's 1:30am. I have to get up in four hours!
