Steam only uses two stars. Recommend or not. And devs still get sad about "negative" ratings. But honestly, the rating system calls it by name. Would you recommend this game? Yes/No? But it lacks context. It would be better if it would read: would you recommend that game to players that share your taste in games? We all know our vanity games. We might like them a lot, but might not "recommend" them.
But they do use public reviews, so people can browse those and read up why exactly the games are recommend - or not. Itch does not have those, probably because of the nightmare it would be to moderate those and the whining of the amateur devs that get two reviews and one of them is negative and unfair.
Oh and look, a reply in an undeleted thread. Might be coincidence, but you know what I mean. Also, about that nightmare, the reviews on Steam have comments and their own ratings. The rabbit hole is deep there.
