i don't even know what logic would compel you to believe this was ever going to be a thing. majority of this games players didn't complete the single campaign. Rockstar can see the stats directly. I've been saying this for 10 yearsI'm that one dumbass still holding out hope for GTA 5 single player DLC
there was an influx of new players over the years who just went straight to online. online sustains this game and has made it relevant for a decade. a solo campaign is so far out the picture man
