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 like all manners of 4x and grand strategy games, though i must say that even though i don't play in Civ lately, it has been possibly the most consistently fun series of all strategy games, i enjoyed all games greatly except Civ 3, which makes it a whooping 5/6 great games (and Colonization and especially Alpha Centauri were also good).
