Have you any idea how many pop culture references AKA
"Easter Eggs" there are in Fallout 1? The bar in the Hub is called the Maltese Falcon after the famous Humphrey Bogart film. Mentats are super-intelligent humans in Dune. Dogmeat's owner is a freaking Mad Max expy.
Ect. Ect. Ect.
A (not-complete) list of easter eggs littered all over the main game you say don't count:
http://fallout.wikia.com/wiki/Fallout_cultural_references
Funnily enough, only the first in that list is a random encounter. So how can "easter eggs" not count when they make up a substantial chunk of the game? You can't pick and choose. The truth is that Fallout was like that from the very start. Fallout 2 simply took it to 11 and Fallout 3 ironically enough toned it back down.
You do not get it at all. References, or in the case of Fallout 1, the SERIOUS use of fitting names/look-alike scenes taken from cultures for a drug increasing intelligence, a bar, the story of a other traveler you never meet, and ect, are all well INTEGRATED within the world. They aren't stupid and out of place. They are serious and serve a purpose.
You can't compare the serious use of culture in Fallout 1 with the freaking circus of Fallout 2. And don't use the random encounters requiring 9 or 10 luck as a 'argument'. I only saw them once in 20 years and who know how many times of playing Fallout 1. Even these special encounters are more subtle than most of their counterpart in Fallout 2, and worst, some out of place situations staring you in the face in every playthrought.
Can you really compare the use of the name 'mentats' for a well integrated element, with the 'chosen one' quoting the Godfather out of nowhere and for no valid reason, a man stopping you at a bridge to outright ask you 'what npc in Fallout 1 also exist in Fallout 2?'
Stuart Little can quote X-Files, really, because it sort of fit the conversation where he can do that. However he start telling you outright that he know it's all a game and that 'they were limited in models during the development of Fallout 2'.
No, the chosen one can't possibly have seen Hannibal Lecter on holodisk and I don't care how many pre-war gadgets he may have found by the time he get to San Fransisco.
I could go on but my point seem clear to me. In case it's not to you, then don't speak of things that went completely over your head. Fallout was not 'like that from the very start'.
