Is it a time suck on the level of Factorio? I've been interested in KSP, but can't afford to lose a month of time like with Factorio.
And in 1 hour without ever having played in KSP you probably can lift of the ground and maybe go straight vertically out of the atmosphere.
If you do have a human being teaching you the first hour you can go to orbit definitely. Something as stupid as "you don't go to orbit by going vertically" is very helpful for an inexperienced player.
