Death Stranding came out in 2019. Death Stranding 2 will come out in 2025. That's six years for two games. If these were the PS2 days Kojima would have cranked out 3 Death Stranding games by now and we'd be getting Death Stranding 3: Subsistence along with a teaser for Death Stranding 4 next year.
Remember when video game trilogies used be to a huge thing in the sixth and seventh generations? You'd typically get 3 games in about 5-7 years
See: Halo, Gears of War, Resistance, Killzone, etc
Elder Scrolls 6 is pretty easy to explain, they simply were not working on it, focused entirely on Starfield. That teaser from years ago was a distraction to make you think they were still working on it, and to get shareholders to shut up about them not putting out the next installment.
90% of my interest in Elder Scrolls 6 evaporated when I read that Starfield was the basis of the game's engine and that the upcoming game would "continue the exciting exploration and discovery themes of Starfield."
I'm more interested in that Daggerfall spiritual successor honestly
Where's my Redguard sequel.
