I think they broke something with the radio in NV, in F3 it would dim down heaps whenever you're in a conversation but for NV it's ALWAYS at a constant volume and it's hard to hear people talk sometimes.
And even though there are more tracks for the radio in NV they all seem to- Well... They got boring a lot faster than F3's. I think they missed the mark on the radio elements in NV by a long shot.
