With WoW, you can end up doing things like "running a guild" that is not entirely dissimilar from "running a business or an office of a business" and training up other real skills that are valuable to real business. I can well believe there's some people who just sort of slid into doing that sort of thing, and one day had the revelation that if they can do this, they must be more capable than various other elements of their life had been telling them they were.
I'm not sure I'd recommend it as a path to explicitly seek out per se, but if it's one you're already walking, it's a great thing to realize and be empowered by.
