I guess you're right about it being a way to for small creators to get featured. I got the idea of it being a large source of traffic because I was counting post views as visibility, because it kind of is. I saw about 10-20 views on average of the posts, and I could reasonably see that as being half of a game's views if the creator decides that that is all the marketing that is needed. Even though it might not be game page views, I still count it as traffic because it serves the same purpose as a game page, (which is trying to sell someone on your game) but it just takes an extra click.
