I was going to be all whiney about "hitting a complexity wall" in my flight sim, but then I realised: I wasn't writing a flight sim! I was writing a terrain generator, and that's working great!

I do want to write a flight sim (or at least, some kind of game where the control system is kind of aircrafty), so I should think about that, but I should start with a blank sheet and build it up properly.

Mostly, the choice I need to make is how much of the low level graphics stuff do I want to do, and how much can/should/do I want to hand over to a library (twgl and three.jshttps://threejs.org/ are the current options).
