Hello DYKG! I've been a fan for a long time, and I love the work that's put into this show, but I could not help but notice that you haven't really talked about Fallout, despite it being filled with fun stuff.
So I'm going to lay some of them on the table, and then I'll let you decide. I tried to find some on the forums, and while I found a few I thought that I might as well include them here too, so they are all in one post
In Fallout (1997) you can encounter a blue phone booth, like the TARDIS in Doctor Who, when you explore the wasteland. When you walk close to it, it will teleport out of the map, leaving behind a Motion Sensor
In Fallout (1997) you can encounter a crashed alien ship. In this ship are two dead aliens, one bearing a strange blaster, the other a picture of Elvis "The King" Presley. In Fallout New Vegas (2010) there's a whole gang focused around an Elvis Presley picture they found. They call themselves "The Kings". You can read the side of the crashed Alien ship, and if you do it says "Property of Area 51: Return if Found"
In Fallout 2 (1998) you can encounter a pack of Brahmins just standing around. If you get too close to them, they will walk slowly towards you, and if they hit you they will explode, pretty much killing you instantly. Whenever one dies, another one spawns.
Probably the most interesting one: In Fallout 2 (1998) you can encounter something called "The Café of Broken Dreams". It's a café where many of the characters from Fallout 1 is sitting and talking with each other and the player. There's companions from the first game, commenting on how they thought the game were played, and there is even a guy talking about how this one guy actually made Dogmeat survive the last mission in Fallout 1. Since the last mission involves setting off a bomb, your companions can't make it out before it blows, but this one guy was so smart he kited the dog through laser-walls until' he was at a point just outside the blastrange, thus surviving. If you have your default armor on (The vault suit you start with) Dogmeat will recognize the armor and join you.
There is also NPC's talking about how they never got included into the game for various reasons.
Project V13 was a Fallout MMO that was shut down before it could finish. The only thing we've seen from it has been scarce screenshots and a short intro movie. What is strange in this movie is that you see a desk, and in that desk the words "THE MASTER LIVES" is carved. The Master is the badguy from Fallout 1, considered by many to be the best antagonist ever made in a video game, and you most definitely kill him. Maybe they planned for his return?
RUMOR: In Fallout New Vegas, there should have been a whole new zone where you could go to Legion territory and see how their system worked. In this zone there would be no raiders nor mutants, because as they promised you, when you live under their wing you are safe. This zone was supposed to make the player see the civilized NCR lands from another viewpoint, with a clear message that Legion is as Evil as NCR, and NCR is as good as Legion. Unfortunately, Obsidian didn't have enough time to make this zone complete, due to Bethesda's deadlines for the game (And their cutting of financial support) which finally led to the whole zone being deleted.
In every Fallout game, the Leather Armor looks exactly like the armor Mel Gibson wears in Mad Max, since the games are very inspired by those movies. There is also tons of references to older post-apocalyptic movies like On The Beach, Road Warrior and City of Lost Children.
Fallout: New Vegas, with its 65.000 lines of dialogue, is the game with most dialogue ever made, beating even games like Planescape Torment, Witcher and Final Fantasy VII.
I have tons more, but this should do for now
I'll keep this thread updated if I find more interesting things. Until' then, stay out of The Glow, and may the Wasteland be kind to all of you
