Some ideas for them as simple scripts similar to what is on SIC currently but would make them seem more alive:
*Random Chatter heard over the radio - deaths? Random events? Something completely new?
*NLM Radio Show or News - Possibly could be player done but I have wanted radio content during car rides for ages. Could be things like the dome weather, deathball scores, random blurbs about recent news events (Last night, there was a mugging in New Light Station, the WJF is seeking two perpetrators who looked like x. Now on to the weather with Stormy Weathers.)
*Badlands Emergency Radio: Similar to the NLM radio show, but akin to the emergency band on boat radios IRL. Gives weather changes, information about it, the time at intervals. Would be an interesting addition given the changes in weather in the badlands not necessarily being linked to dome weather.
*Radio dramas/music - Old NLM scripts transferred to radio? New things that are player driven. Whatever, things to listen to that aren't ad screens. An option to have NLM stars record their songs that are played on the radio interspersed with simpler things like ads that go like (The next song that plays is the latest Juicy Vee song, The Tale of McSwizzle, Joy of Knife Street) to make it not just a solid block of text.
Other ideas are great. I just feel radios at this current time, while they have great potential, are underused because there are no good examples of use for them for players to build off of.
