The results are in, and it's a tie. It has been an interesting research process, and despite GotGame's hypothesis, storyline-based and graphics-based games currently share the majority of Steam's popularity contest. The PC gaming market is a very broad one, and good thing, too. It looks like every angle of research production (when done well) is given its due. At least for now. In looking at the top six most popular games currently being sold on Steam, the score is 3 to 3.
