This is sad, at one point I played KSP 1 a lot and I agree it didn't need much upgrading. I had been hearing about KSP 2 for a while but hadn't really followed it. I'll fire up my old copy later today in loving memory...
Also ksp1 was barely playable without mods (the last time I played it)
Interstellar, long term bases for jump off, more interesting science mode. There could be a lot that they could have added to ksp2. But its yet another indie darling dying on sequel.
