Don't know if its been addressed in this thread yet, but speaking of Broken Steel, Three Dog always talks about "two weeks...it's been two weeks since the brotherhood kicked those enclave bastards out of project purity and got that baby chugging" (off of memory, not 100%). Anyway, he says this line before completing main quest line.
Not sure if this is a bug, but doing the Galaxy News Radio quest, you go through the Museum of Technology. If you happen to pass through the Planetarium, you're in for a real treat. From the moment you step inside, you will hear a small speech repeated over and over until you go back to the main entrance. Finding the terminal and selecting "Stop Show in Progress" does nothing. I beg of you, please make this selection shut that man up.
I'm not alright, I'm an equal amount of left.
