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
I'm actually certified in a version of SCRUM. I've been on a total of one project which did it in what I would say is the correct way. Where the primary purpose was to gauge work and plan around the developers capabilities and needs, instead of having deadlines imposed arbitrarily from the top. It worked great and we delivered a useful tool in a relatively quick period with pretty inexperienced devs.
Every other time though it's a poor excuse for managers to waste time with useless metrics reporting and whip the devs into coding faster.
