I think CS:2 was far too ambitious, and there were very strange design choices around subsidies which effectively removed any challenge from the game – at first. I just played it the other day, and frankly it has turned around a lot. Decent game now.

KSP2 was just a corporate shit show – devs were well intentioned but ultimately were unable to continue based on factors out of their control. It really sucks because KSP1 is one of the best games ever made and KSP2 had a lot of promise.
