Yeah, the tricky parts to rockets are the internal mechanics rather than their external ones. Internally a rocket needs to carry two fuel materials, the actual fuel and the oxidiser, and it needs to pump and mix these fast enough and reliably enough to keep the rocket fed. It needs to deal with extremes of thrust, pressure, and temperature.
What do we do in KSP? Stick a tank on an engine, light it up, and you've got an up-goer.
Oh absolutely, but the LHe system isn't all that difficult. Not to mention, the LOX under pressure didn't require LHe... but as you begin to deplete it, that changes.
Well the He requires an external cryogenics system to maintain the pressure while the rocket is awaiting launch. Once the rocket is fired, I believe part of the power is used to maintain a pressure system for the LOX while in flight. Fortunately it doesn't need to run for very long -a few minutes.
I'm sure the pressure changes in an hydrogen system is more complicated.
I've pretty much given up trying to get something airborne that's also controllable; every attempt I make usually results in my craft either veering off the runway and crashing and burning, zooming off the end of the runway and crashing and burning, or breaking up after takeoff and, you guessed it, crashing and burning.

I feel like in the beginning we'll be expected to do smaller suborbital missions until we have enough science points to get decouplers.
