Just throwing in an additional idea:
Make the radio station an object you can build in one settlement and make it location-aware in the way that the news anchor can say from where he's broadcasting. I'd imagine people would want something like this in a sprawling wasteland town. Hell, you could even have some specific lines about what crops they're growing, if any. I know this is lots of VA work but damn.
Or at least make the station an actual place you can visit.
An interesting idea for an addition. But right now, I think the project 'as is' is going to be a lot of work.
I'd still like later versions of the mod to include new, popular lore-friendly mods AND a unique quest mod.
However, if you would like to work alone on the quest portion of the mod, I can write up a script for the quest. But there's some issues:
1.) Need time to write up the script. Gonna take a while. So you might be waiting a while.
2.) You would be working with Pra and all the other mod authors interested on how to integrate your work with their's.
3.) Also need you to pick up the slack when your part is done. So your going to have to commit to bringing this mod to completion.
If you'd like to experiment with how your idea could work, you may as well do so now while you wait.
