Hmm, if I may add to the discussion, I think it's because Fallout 2 was quite all over the place. Fallout 1 was so interconnected, so coherent, tight, and solid, that thinking about it over and over it's a shame Fallout 2 can't follow Fallout 1's steps in that regard. In an average playthrough of Fallout 1 (spanning from between 15-20 hours, based on my experience) you might encounter an easter egg or two, but never 5 or 6, out of 14 http://fallout.wikia.com/wiki/Fallout_cultural_references. This is thanks to the double stage of time limits imposed upon the game. Meanwhile, not only Fallout 2 is two times bigger than its predecessor, it also got rid of the time limit altogether. Chris Avellone admitted that the development of the game were quite disjointed because each subgroup of the team mostly keep to themselves, no one communicate with one another and, because of that, each subgroup just adds their own references. This, together with the fact that it's a much bigger game AND have no time limit whatsoever, means that in an average playthrough of the game (somewhere between 60-70 hours, could even be 80 hours with RP and based on my experience) you can encounter like half of ~90 references in the game http://fallout.wikia.com/wiki/Fallout_2_cultural_references. (Mind you, I also haven't taken into consideration that some of these references WILL be encountered no matter what) Yes, games like this aren't supposed to take themselves seriously 24/7. But in case of Fallout 2.... it gets really annoying after a while. These days, on my nth playthrough, encountering an reference only makes me roll my eyes in annoyance.
