I fly and die in Orbiter as well as KSP. The two are complementary. What KSP lacks in fancy instrumentation and places to go (so far) it makes up for with sheer craziness. If only I had two PCs side-by-side so I could conveniently play both at once! Strangely, although I can see the faces of my Kerbonauts, both terrified and nuts, I feel more relaxed about slaughtering my crews in KSP than Orbiter. The seriousness of Orbiter makes me feel as though real people are at stake. Of course, this hasn't stopped me from, say, bungling a Luna-Earth return trajectory and asphyxiating a CTV crew... ???
