100% yes, that XKCD thing is 100% accurate. Kerbal taught me 99% of what I know about orbital mechanics; my (near-complete) PhD in astrophysics only accounts for the remaining 1%.
(You can tell I'm a science guy because I used loads of percentages.) (Also I hope you don't all think I'm humble bragging (I bet you all do though))
I played a lot of simple rockets when that was new and I've heard it's got better and better since but I haven't been playing it regularly. I'm assuming KSP is much better due to the available processing power?
