They had a system to connect developers and "influencers". It was abandoned, because people just used it to download paid stuff for free. There are still traces of that system.
But still, for some games, a little info easily reachable on the game description with those press kit infos would be nice.
They could add a searchable metadata thingy, so interested streamers could easily filter the developers that made the effort to include such press kit infos.
I am talking about the filter stuff that are in the left side of browse, where you can add useless stuff like input method and session length.
Some of those filters are even undocumented. I know there is the filter "released" and "in-development", but I do not know where the button in browse is, to add that filter.
