Also, lots more snippets of things happening around the wasteland would be appreciated. At first, in Fallout 3, it was cool hearing whatever you had caused being talked about on the radio. But after a while (and I mean a short while) you had looped through everything Three Dog had to say and the ONLY news he had was whatever you were up to. This didn't exactly help the overall feeling of you being the only active participant in the world that Falout 3 already suffered from.
You could even pick up quests by listening carefully to the radio transmissions. Stuff like "huge explosion was reported west of Turmoil Hill yesterday, no reports of any casualties", and when you'd go west of that place, you'd find something had happened and a quest would trigger.
Ok, my point is: the radio was a good idea, badly implemented by Bethesda. Let's hope Obsidian expands on it. It has potential to be a great asset to the game.
