this can be on whom you would have liked to seen/mentioned in any fallout game i myself would have enjoyed seeing or hearing of fallout 3 mothership zetas paulson in new vegas as he would have been right at home in that area.

Hmmm... Only one character springs to mind. Was kinda neat seeing an Older Maxson, but I'm kinda curious to see Reilly of Reilly's Rangers again. Even if it's as an old woman in combat armor.

I agree with @IIHawkerII, Reilly would be an interesting person to meet again. Along with that, I want to also see more of Butch and the Tunnel Snakes, who btw rule. I'd like to think that their group has expanded and became a large faction in the Capitol, similar to the Kings. It would also be interesting if there was a 'war' between the Tunnel Snakes and the Atom Cats. The winner would be the coolest one around, and the loser would be labelled as squares forever as punishment. Hell, throw in the Kings into the mix while your at it.

Would be nice to come across some reference to Sulik from Fallout 2. Apparently his sister started the Twisted Hairs (the tribe Ulysses was from), so if any game is set in Legion territory it'd be nice to find out whether Sulik ever did find his sister or not. Or at least some reference to his sister in the game would be enough.

Another cool cameo would be Goris, the intelligent deathclaw looking for knowledge in Fallout 2. I'd love to just have a random encounter with him or better yet, find him as a fully fledged quest/companion. Like Sulik, it would just be nice to know what happened to him since the events of Fallout 2. Although unlike super mutants (like Marcus) I'm not sure how long deathclaws live for so the forty years between Fallout 2 and New Vegas may be pushing it. But some reference would be nice at least, like how Raul is a nod to Vic in Fallout 2.

I think it would be pretty cool to see The Lone Wanderer from Fallout 3. Not much is said of what happens to him/her after the Broken Steel dlc. Correct me if I'm wrong but following Fallout 4's timeline, The Lone Wanderer would be around the age of 30. Plus, if MacCready made it from the Capital Wasteland, why can't he?

Since if benny survived the fort he just kind of upped and disappeared it would be neat if he popped up in a future fallout game, even if its just a reference in note or something of that form

@"IIHawkerII" yeah it would be pretty cool to hear ov Reilly again it would be neat to hear her being able to build the Reilly's rangers to match or even out number the talon company mercs @"Y0ungRe13el"   that would be pretty RAD {lol get it} to see that match up although id say the Atom cats would come out on top cuz tank suits {just my two bucks on it} @"Visible Earth" Goris is someone i would have loved to hear about and had a quest for in a way i could see him with the followers of the apocalypse "shrugs" @"Constable Canada"  i agree there should have been a little more on what happened after the events ov fallout 3 and it's DLC hell for all we know the lone wanderer is defending the earth from aliens and thats why more ships keep crashing haha

From Fallout 3 I'd love to see Fawkes return as well as all the characters that stayed aboard mothership zeta like Sally, Toshiro Kago, and Elliot.

It'd also be awesome and make sense for Raul the immortal wandering gunslinger from ol Mexico to show up in a new wasteland.

An surviving Enclave soldier. That is the one and only cameo I want to see in the upcoming game. Then when you see the guy/girl, he/she will be like telling you what happened to them after FO3 and the NPC will give you a quest and upon completion....a full set of customized Enclave Armor.

Seeing any of the member from the Lyon's pride would be cool and hearing what they think about Maxson or the death of Sarah.
