Do you see a flight sim on that list, or even a game with a plane in it? There are MMOs, RPGs, shooters. That's the games market. That's the PC games market in specific.
SOW:BOB occupies the tiniest of genres out there that absolutely no one cares about. That is why the only flight sims being made are now coming out of Russia and why Microsoft killed Flight Simulator and the studio that produced it.
Wake up, folks. You are in the smallest of minorities. No one has heard of this game. No one will ever hear of this game, but a very select few in the PC gaming market. SOW:BOB is being anticipated by no one. The sooner you can come to terms with that, the better.
