Not a death, but eh.
I didn't have the generosity to pay off the mercy outside of Jacobstown, or whatever it's called, and had to kill them. I forgot they were NCR, so Boone got pissed and left me there. Additionally, I got put on the NCR's shitlist because of this and all the other crap people had been making me do. I was walking away from the town to go to a nicer place, and then...
*SssSsssssSs*
[Quest failed: I forgot to remember to forget]
I couldn't find Boone's body, so I couldn't mourn him.
Caesar gave me a semi formal invitation to come see him, probably because of the mercenary incident. The only reason I went was to continue my vendetta for Benny, who had ambushed me earlier even after we seemingly came to an agreement. I had killed his henchmen with my bare hands, and now I was going for him with a renewed thirst for vengeance.
I didn't dare try to fight Caesar, due to his intimidating Ballistic Fist. I spoke with him, and politely told him "Fuck you, I'm not going to help you take over NV" several times, only to be met with more commands. He gave me the platinum chip and told me to do something I can't remember, I answered "BITCH IMMA SHOVE THIS CHIP UP YO ASS" and did, then he punched me so hard I exploded. Repeat the above, only this time I didn't try to fight.
I attempted to leave with the chip, and go speak to Mr. House as he's the only kind-sounding person left who doesn't hate me. I had to leave it at the Legion fort, which is probably why the game isn't letting me say "Yes" to Mr. House.
Screw everything, I'm this close to going on an adventure to kill everyone in New Vegas. It seems like the only plausible solution now, since my friend is dead, my allies hate me, my enemies are using me, and my nemesis escaped.
What have I gotten myself into?
