You should know Frank, (if you just don't know already) just a fun fact-ish thing, fallout new vegas I presume was probably intended to be much more in terms of the first fallout 1 and 2 in the form of quests and dialogue. (at first) If you remember the solar power station Helios I, and the dialogue and quest parts and all that good shit, you'll notice it's all exactly in the same respect as the Fallout 1 and 2.
Why though it was not put into the entire game? I believe the intended to do the whole game like that, but were cut off, but decided to leave that bit in there. Why exactly I cannot seem to find the answer anywhere. Though it's off-topic, I always found this little thing very amusing. I hope the next one they make will be total scheme as such, but it is unlikely since it got cut in the first place.
And yeah, what cannotspace said

Have you at least played the games izual? Or perhaps you only played the clearsky which was the worst one
