He took all of the talent with him and Rockstar had to hire a bunch of college grads to replace them.
Rockstar is so fucked. We're gunna see even more mobile phone game shit and vapid virtue signaling in the next game they make. All they have left is the Hauser brothers and they have consistently fought with the team to cram movie bullshit and awful features into every game.
The Hausers are responsible for the mess that was GTA IV's dating and relationship system. They're also responsible for the baby-like borderline on-rails "Go here, Kill that, AND YOU BETTER NOT HAVE FUN OR I WILL TURN THIS CAR AROUND, MISTER" experience that Red Dead Redemption 2 was.
This whole thread reeks of british children anyway. I don't expect you to know a goddamn thing about quality vidya.
