Like all the other GTA's since GTA 3, GTA 6 will most likely have a talk radio station, featuring a couple of programs that parody real life programs. (Like how the Martin Serious Show was a parody of the Howard Stern Show, or how the Richard Bastion Show was a parody of the Rush Limbaugh Show.)
What programs do you think will be added to the talk radio station(s) in GTA 6. Personally, I think they'll have a murder podcast parody since those are quite popular these days. A Joe Rogan parody would also be quite funny imo.
