Your Favourite Feature in KSP

The first time I landed on the Mun. Flew to the tip of the crater using the suit and looked back once I reached the top. Saw Kerbin. Brought a tear to my eye. I was an astronaut lost in a deep sea of silence. My favorite feature? The experience of being alone with your ship landed and looking at the Kerbal version of The Pale Blue Dot. This made me feel like a kid again. Thank you devs for this.

The open universe. The fact there are no scene changes between launch, orbit, interstellar travel etc. In every other 'space game' there was always some 'warp', or other 'border'. Here the only such 'border' is between KSC/VAB/SPH and the flight - and even THAT is mostly removable with KAS and OSE Workshop. I mean, I spent last week on Gilly and launched a good dozen vehicles - without ever entering VAB!

Jebediah Kerman's grinning face was the thing that sold me on getting KSP in the first place
