There is an affiliate system on itch? Like with curators reviewing games and such? Where?
Is this a new feature or an old and abandoned concept? Because reviews are not really very public. Actually, there are no reviews at all. Not like on Steam. You cannot go to a game page and read reviews for a game.
In theory there could be "influencers", non game developers, with many followers on itch. When they would rate a game, that comment would appear in the feed of their followers. I have yet to encounter such a thing on itch. If itch does promote such a system, they do it very silently, or maybe I have not looked in the right places.
