I recently just finished Fall Out New Vegas for the PC. That last guy with the sword was IMPOSSIBLE, my speech skill was high enough that I could talk him out of fighting which I did, but not after A LOT of tries to kill him. I feel like I "soft" beat the game. Still a lot of game breaking bugs 2 years on, I guess after they didn't get the publisher bonus they shelved any ideas of fixing the remaining issues, can't say I blame them.
