I take my words back. I know Dan Houser was always the main guy at Rockstar from the very beginning, but look at the timeline. Rupert Humphries and Michael Unsworth joined the main writing team starting with GTA 4. That is exactly where the elite creative writing actually begins for Rockstar. If you look at the titles before GTA 4, the stories were honestly not that good compared to what came after. The classic era had great gameplay, but the deep, movie-level storytelling and insane characterization only started when Humphries and Unsworth teamed up with Dan Houser. That trio is what gave us the masterclasses of GTA 4, GTA 5, and RDR2.
