I prefer thinking that a semi-pro, niche market, is very different from mainstream. And you can have general purpose stuff (think, google docs) which can do easy tasks, but for a more complex task you'd need a full office suite.
If you can, or want to, tell the difference between a simulator, and an arcade with some strategy game, fine. But those are (and probably will, for quite a long time) be different things. I just still hope we won't run out of sims!
