I take it you mean DCS by this? Perhaps easier than the things in Il-2. I use a gadget called www.pointctrl.com to emulate a mouse in VR and I just click the things I need controlled. So the things that are on the hotas in the real machine are, and the rest gets pecked at. It’s hella immersive.
I wouldn’t write off the modern stuff as ridicilously complex. Yes you can dive into the nitty gritty and count every rivet, complete every procedure and drop GPS guided weapons on four different targets in one pass. Or you could just, you know, shoot stuff with rockets, guns and heatseekers. Get a jet like the F-86 and there’s even less complexity to deal with than a warbird as the engine is way simpler to operate.
Afaik VKB don’t make a throttle yet but are planning to do so in the future.
