Totally agree with you. During the height of my KSP addiction, I wrote a binder for Orbital Transfers. I can basically lookup the required angle and dV for a transfer from any orbit to another orbit between any two planets and if not in the table, make a good approximation (and then just eyeball it from there) It's probably my #1 Game that I would have my kids play, if I ever have some, just to teach them what real space physics are.
