Oh okay, yeah, that is what I did for Fallout 3. I was thinking of starting it, but I decided to finish Kingdom Hearts Re: Chains Of Memories instead; so far, in about 2 days, I am on the 10th floor with Sora. I have been basically spamming Slights, so decided to make a Proud Mode walkthrough, as the Trophy details do not cover too much details on how to progress.
I'd rather Vanquish again if that ever happened to me. From what I can remember, it took me forever to fully complete New Vegas; also I hated the Legion, the NCR and House were okay folks to say the least..
You certainly must have a lot of patience to play that game. From what I can remember from Xbox, it was a painful experience for me. However, the one perk I absolutely wished they had in Fallout 3, but do not was the Jury Rigging perk - best perk EVER.
I'll more than likely get it to have the whole Fallout collection again, but I may need your guide, or you for any additional info.
