I'm a student games programmer in my final year of University. I absolutely love KSP as it has given me a greater understanding of the difficulty and science behind real life space missions!
I really want to make a simple 2D space sim game in order to buff out my portfolio (and for fun of course!). I've looked everywhere on the internet and forums for suggested methods of programming realistic gravity physics for orbiting etc. The problem is the methods I try are inconsistent or unrealistic... Looking at KSP it looks like they calculate trajectories and then put the ship on rails
