KSP2 is a unique situation, there are no improvements coming because the studio was shut down. I'm not sure the others belong alongside it. I have the most experience with CS2 and I can say confidently, even at launch, it was better than the original in a lot of ways. It was buggy and unoptimized, and lacked content, and it deserved the criticism it got for those reasons. Since then, most of the bugs have been ironed out, performance is way better, and they've released a bunch of content packs, several of the most substantial ones for free. Even at launch, I never wanted to go back to CS1 just because of how much better the road tools are. Now? No contest. CS2 is a great city builder.

On the one hand, I'm glad for the pressure that people with less patience than I have are applying to these companies to release their games in a better state. On the other, I think there's a lot of unwarranted criticism and vitriol that goes along with it that's disappointing to see.
