Bethesda Exec Says It Could Take 130 Hours Just To Get Going In Starfield
During a livestreamed appearance at Gamescom, Pete Hines—Bethesda's Head of Publishing—told a story about how, earlier in development he had been playing the game and gotten some 80 hours into a playthrough when fellow Bethesda honcho Todd Howard asked him how he liked the main quest. Hines replied that he hadn't even started on it yet, which apparently prompted an alarmed "what are you doing?" response from Howard.
Hines went on to say that the main quest story in Starfield is his "favorite Bethesda Game Studios story," and that it also has his favorite ending. We don't know what that implies yet, of course—as Hines himself says, Bethesda has refrained from talking in any detail about the main quest of the game to avoid spoilers—but Bethesda did reveal that Starfield will be its first game with a "New Game+" mode.
With that in mind, it's possible that the main quest in Starfield is sort-of like an extended tutorial where you don't have all of the game's mechanics unlocked until you complete it. It's also possible that finishing the main quest puts you into New Game+, a fresh start on the title with all the abilities you gain during the main quest. Whatever the case, it seems clear that Starfield has a richer and more involved main quest than previous titles from the developer.
