KSP isn't nearly as realistic as Orbiter, but I personally see it as a good thing because it makes the right simplifications to give even a 10-year old a reasonable chance at developing an intuitive understanding of orbital dynamics. Said 10-year old won't be able to plot a real trajectory for a rocket/satellite, but giving a 10-year old an intuitive understanding of inclination changes, gravity slingshots, Hohmann transfers, etc. is an amazing feat by itself.
