I liked a lot of the characters. Desmond Lockheart, 3 Dog, Dad, Sheriff Simms and Paulson from Zeta were my favorite characters in fallout 3. I also got a kick out of Mayor Maccready from little lamplight. For New Vegas, my favorite characters have to be Joshua Graham and Ulysses. They both stand out so much in the game and are both pretty well written characters (In my opinion).

Lieutenant Carrie Boyd I have always had a liking for. She doesn't play a big part in the game but her voice actor was amazing in Saints Row 3 and 4, Resident Evil, Skyrim and Bloodrayne. She reminds me sort of the female sole survivor with her sassy badassery. She is my favourite NCR member, and her voice actor I would love to see in future Fallout instalments.

I haven't played FO3 or FNV for quite a while so I've probably forgotten a lot of the characters, but while playing Fallout 4 I've been reminded how much more interesting the companions of FNV were but in particular I miss Veronica. People may think she didn't have the most interesting backstory but she definitely had a lot of character.

One character I'm really fond of from Fallout NV is Chief Hanlon, he lead the NCR to victory against the one and only Joshua Graham. Although I agree that Joshua Graham is a fascinating individual because he's unique, but he was bested by Chief Hanlon during the Battle of Hoover Dam. To beat someone so feared and has the will power to endure the worst physical and emotional pain and come out alive, that takes some skill. In addition, it just adds to the astonishment that in his old age settles to a latter camp glazing over at the Lake Las Vegas telling tales to any interested passerby.

Fallout 3 the character I'm most fond of is Sarah Lyons. The reason for that is because she was such a strong female character and etc. Idk I just liked her for some reason. But anyways too bad Bethesda didn't make her an available companion after the Broken Steel dlc. Disappointing. For FNV it was Ulysses. He was mysterious, has that cool vibe to him. Idk he was just a BA character in general for me.

Honestly speaking, in Fallout 3 it was Moira Brown. She was just so happy with everything, even if she puts me in crappy situations. But hey, nothing beats making a "Dummies Guide to the Wasteland".

I can't think of any in Fallout 3, none of them were really that memorable. I suppose I like Ashur from The Pitt DLC.

NV on the other hand had so many great characters it's hard to choose. My favorite is a tie between Joshua Graham and Raul Tejada. Oh but then there's Caesar, Ulysses, Cass, Arcade, Chief Hanlon, Sarah Weintraub, Dean Domino, Mr. House, Lanius, and way more than I want to list. Don't make me choose.

Oh and who could forget Snuffles?
