In a generation that has had its fair share of huge PlayStation 4 titles, both multi-platform and exclusive, delayed time and time again, Death Stranding feels like an enigma. Developed in the space of three years, Kojima Productions has managed to put out 2019's biggest title probably at least 365 days earlier than anyone thought it would.
not having to code an engine of your own is a start
Japanese devs are a whole different beast, they have very different pipelines and very rarely run into the issues western devs have of constantly adding, subtracting and changing aspects of the game till the last minute. They also dont focus so as heavily on developing NEW technology and instead primarily use tried and true methods and technologies. They are just a lot more efficient generally. Shadow of the colossus was built wuth a team of 23, and the last guardian with about 40 (with final push of getting to gold helped by santa monica studio) thats just how they've always been. Of coarse there are exceptions but generally thats just how they roll.
I wouldn’t call Death Stranding 2019’s biggest title
In reality, Kojima was probably working on this as a side project while making MGS. From alot of the Death Stranding theory vids that are out there, apparently P.T. aka Silent Hills got reimagined as Death Stranding.
Amazing what a plan and hard work will do.
