Buy Honest Hearts expansion for Fallout: New Vegas. Everyone in my group immediately killed. Named NPCs shooting at me and trying to kill me, no one to talk to, seems odd, shoot back and kill them in self defense. Walk to opposite end of map and get a map. Fast travel back to beginning location. Honest Hearts is over. $10 for 5 minutes of completely plotless gameplay.
I'm aware that it probably bugged out or something, but that, uh, doesn't make it okay.
