Hidden object games are a fascinating demonstration of the arbitrariness of genre as a marketing tool because sometimes a game with "hidden object" on the cover is basically a digital version of Where's Waldo, and sometimes a game with "hidden object" on the cover is a full-featured point and click adventure game that just doesn't call itself that because its target audience is your middle-aged mom and the phrase "adventure game" doesn't sell for that demographic, and there's absolutely no way to predict from looking at the promotional material which of those it's going to be.
And then every few years the games industry goes "ADVENTURE GAMES ARE DEAD AND HAVE BEEN SINCE THE 90S AND NO ONE HAS MADE ONE IN YEARS! LOOK AT WHAT A STRANGE RETURN TO FORM OUTLIER THIS ONE THING WE'RE RELEASING IS."
Yeah, it's long been my contention that the preponderance of evidence suggests point and click adventure games never really "died" – they just became persona non grata with the gaming industry's promotional apparatus because because their player demographics started to skew strongly female for various reasons, and to this day the industry remains allergic to acknowledging that women play games.
