Just wondering if anyone does it, has done it, or is interested in doing it.

I've been doing it for about ten years. It's a blast, and one of the few "indulgences" I grant myself. I'm usually tied up at work, or working on the house and the cars. This is the way I get to "escape" and do something I enjoy that I'd never have the chance to do in real life. Besides, I'm getting up in years and don't heal as quickly as I used to, so the "simulation" part is perfect for an old guy with limited resources.
