FWIW, I just want to corroborate this. I've been very focal laying out what I appreciate about Valve/Steam on this forum, but this is annoying me a bit.This sale the queue has been even more weird than usual for me, showing me a lot of those cheap, uninteresting hentai (in name only) puzzle games the first couple of days. I'd blame myself because I just click next when I see a game I'm not interested in (I'm in the queue for the cards primarily, not to discover games) and wishlist those that actually catch my interest in the few seconds of attention I give each page (I give them more attention if I'm not in a hurry to get my cards and if the title/video/pictures look interesting then i might stop there to read a bit about the game), almost never hitting the ignore/not interested button but as I look at the reason why these games were showing in my queue Steam said it was not because of games I've played, those I've bought, those I've wishlisted, those played/recommended by my friends but just because these games have positive steam reviews, which is a bit of a weak reason to show them to me back to back to back.
I started hitting that not interested/ignore button but then I swear a game I ignored the day before showed up again the day after in one of my 3 daily queues and the ignore button wasn't ticked.
It feels like there is still something weird going behind the scenes.
I had never gotten these weird hentai "puzzle" games (or any "hentai" games in general) until right around when the sale started. Suddenly, I'm getting an average of at least one per queue, and I have no idea why.
I understand that it's partially my fault for having some of the adult content filters off, but I still don't understand where the "discovery" part is coming from. I own very few "anime" games on Steam (Recettear, BlazBlue, GG XX ACCENT, Ys Origin and Oath, and Legend of Heroes is basically my entire collection), and I own almost nothing that would be classified as "adult" (literally the "sexiest" my library gets is The Witcher 1/2). I own no VNs, and haven't wish-listed any either.
And yet, today, even after me hitting "ignore" on like six anime tit games in my queue yesterday, I got another stupid yuri VN and a scalie VN about dragons in my first queue. Then I got some weird AO pseudo-anime VN in my second queue. And finally some erotic gachimuchi puzzler and a furry game that came up with a literal rape warning in my third queue. So that's five shitty sex games in three queues.
I'm not here to rail against those games necessarily being on Steam, and I don't really give a damn if someone wants to play some low-effort "puzzle" game to get their jollies. But I really do not get why they're in my queues. If I'm into puzzle games, and I am, show me actual puzzle games. Not these non-puzzle sex games and VNs I showed no interest in! And I've never bought VNs on Steam, so stop showing me those all together!
If the system is trying to learn or predict some of my tendencies, it's completely off the mark with those games.
