Why video games are great.
If you have any interest in space, rockets, engineering, flying, ect, YOU MUST PLAY THIS GAME. The are no limits, make a giant moonbase, crash a space shuttle into the sun, put a probe in orbit around the farthest planet, or just crash stuff into the ground in a desperate attempt to make a space plane without reading tutorials on how to do so.
This is the next minecraft. Endless creative, moddable, and limited only by imagination, KSP is a triumph of video games. I love it, every minute of it, even when I accidentally de-orbit my space station, Im smiling as it goes down, and saluting the brave Kerbals who gave their lives in the name of science.
