KSP2 made some degree of sense: the game had outgrown its engine and architecture, so you start fresh with a bigger dream.
But before that had a chance to fail from second system syndrome it was doomed to fail by insane demands from Take 2. News of work on KSP2 could harm sales of KSP1, so when hiring people to work on KSP2 they couldn't mention what they were hiring for. So you had a team who didn't know KSP1, and due to budget constraints were mostly juniors. Then to "save time" they were not allowed to only pick the good parts of the old source code or to even switch engine, they were supposed to just expand the janky KSP1 code base. Obviously without being allowed to talk to the developers of that code base, because secrecy. And no talking to fans about what they would want from a KSP2 either, because, you guessed it, secrecy.
So an inexperienced team disconnected from the fan base was supposed to fix a code base they were not familiar with, without speaking to the people who wrote it, add some cool features to it that the original team never tackled due to engine limitations, and release it to massive fanfare. Surprisingly this did not work. As the project was failing went back on many of those decisions, but it's hard to fix a project that starts off so wrong
Compare to Kitten Space Agency: hire KSP1 devs and KSP1 modders so you have people who can judge what worked and what didn't, start with a home-grown engine that fits the unique demands of a KSP-like game, talk with the community during development. Obviously they aren't far enough along yet to call it a success, but I give them much better chances
Ironically, the KSP 2 studio in all their secrecy couldn't help but post multiple videos as early access approached, praising themselves for how innovative and smart they were - how they're so inspired and it's gonna be amazing.
