The game never worked well for me - and now that maybe it might run okay on my far-too-expensive computer, it's clear that KSP2 is dead. The publisher still exists - but now that the company making the game has been shuttered, it's reasonable to assume none of the "Early Access" promises are ever going to be achieved. From this it also means 90% of the store page's content could be classified as False Advertising (which can have pretty serious legal consequences for the publisher and/or Valve).

If I hadn't already put in about 27 hours of 50%actual gameplay (at 10fps) and 50% troubleshooting, then I would at least have already refunded the game.

Don't pay money for lies. KSP1 with mods is a better game. Go play KSP1 instead. :-)
