Sorry. I just reread the comment I made and yeah that looks like some product placement or fake Amazon review.
I can assure you it's coincidental. I posted about a game I recently discovered and then have been super stoked by people leaving their knowledge of similar games that I'm now also excited to give a go. I've recently got into card games and domino games with the kid (a few board games too) and it's all a blast. One of my favorite aspects of HN (have been on here for about a decade, but occasionally lose my account password and have to start over) is the collective knowledge of curious people who know deep stuff about nearly every topic.
That doesn't mean anything lol. I have over 100k karma on Reddit, and I’ve rented the account several times for various astroturfing posts for small startups. You’d be surprised how common that is. (I'm not proud of that, it was 6+ years ago. I wouldn't do it today)
