Radio was a bit hard to come up with something for as most of my characters are sci-fi and radio would be antiquated in their time. I decided to go with one of my favorite single player games, Outer Wilds. I played the alpha back in 2015 and the full release this last year. The game is a hill-billy space program so radio is pretty much all they have. The thing in Oan's hand is a signalscope, which is used to pick up other explorer's instruments. In a few weeks the topic is music so I'll probably return to this game as an environment.
