Stearmandriver, it all depends on the approach to the DCS. For some it's "just a game" for some it's more.
It's great you can fly a real plane, most people here don't. And some of them like to put something extre to this "just a game" wit better HOTAS, makeing a cockpit etc.
We have wide choice of players - beginig with people flying with just a keyboard and mouse, to ones buildng whole cockpit and projector screens or VR. For some it's the only way to be a bit closer to real flying.
It's each ones choice how "real" he want and can go. I'm flying mostly The Hog, I bought TM Warthog (befor prices skyrocketed) and TM Cougar MFCDs. Could I play without them? Of course i could. Is it more fun to play with them? The hell it is! If Jimd wants real looking HOTAS nad has patience to save for it, I say - save, wait and buy it. You won't regret it, and you'll love every second flying plane with "real" HOTAS.
