I haven't experienced any major bugs yet. But my only complaint is... the radio. I loved Three Dog, he was such a major part of the atmosphere of Fallout 3 for me, that not having him there just makes me sad. He was cool and edgy while being a really nice guy. Truth? Mr. New Vegas is just fuckin' weird. He's so sappy and love-happy that it's almost creepy. Instead of a radio announcer that you could laugh with, he's an announcer that you just have to laugh at... if what he said was even funny. Then there's the music. There seems to be less of it, because every ten minutes, I hear the same damn "Big Iron" song. And I hate country, this thing is just all 50s country, and it isn't even the funny kind. I understand... Washington DC was east coast, so you play New York style pop, and Nevada is Wild West so you play 50s Country, but it's grating. And not all of it is country, the stuff that isn't country is even worse ("It's a Sin").
What were they thinking when they picked the tunes for the soundtrack? Fallout 3 we had "Civilization", "Butcher Pete", Aretha Franklin, lots of good swing instrumentals. I felt so entrenched in 50s style pop tunes, that I've written a number of catchy 50s jingles for my TV advertisements! Seriously, Fallout 3 was a good music educational experience. WTF is NV doing for me? Nothing. It's about 4 songs over and over again, all of which SUCK. There's less newscasts too, so he sounds like a broken record.
I just wish they had magically transported Three Dog in from DC. I wouldn't even mind if they didn't explain it. Mr. New Vegas sucks. I'm shutting off the radio until I find a better station to listen to. Truth be told, I'd rather listen to President Edan.
