Last few years I’ve been excitedly waiting for sequels from several small-to-medium sized studios that made highly acclaimed original games—I’m talking about Cities: Skylines, Kerbal Space Program, Planet Coaster, Frostpunk, etc.—yet each sequel was very poorly received to the point I wasn’t willing to risk my money buying it. Why do you think this happens when these developers already had a winning formula?
I mean for ksp2 saying it failed cause they had “no experience with this kind of work” is kind of weird, since neither did the ksp1 devs when they started that. And they didn’t fuck it up either, let alone this badly. Remember that it was a passion project of harvester, working at a PR firm that just happened to let him do it under their roof and employment. The company did not even have any basic experience in game development, arguably even software development in general.
Institutional knowledge is a real thing and also like you said, the first KSP started as a passion project. There’s a huge difference in terms of pressure and expectation between developing your own passion project compared to developing a sequel of a highly regarded game.
