Just short message to say how wonderful KSP is! This is the first game in a long time that has made me want to reach out for the calculator and gets my head scratching on physics that I haven\'t touched in a long, long time. I\'m loving learning basic orbits and tweaking the apoapsis and periapsis on maximum fuel efficiency and ask if there is more recommended reading guides or books out there on this sort of thing, beyond the excellent how-to\'s on the forum and wiki. Looking forward to my first and subsequent many mum shots and beyond! Keep up the fantastic work. Next to go and work out how the pre-payment/donation button works!
