Why did the Dungeon Crawler wane in popularity?

Hi all,

In your opinion... well, to put it bluntly, what the bloody hell happened?

One decade, the only thing people and kids wanted to play were dungeon crawlers, dungeon divers, adventure games, and RPG-adventure board games. Heck, it dominated for 30 years! You know the ones I'm talking about! DragonLance, HeroQuest, Space Crusade, Descent: Journeys in the Dark, and...! Then...! Uh.... oh....

What the bloody hell happened?

Even the videogame side of things couldn't get enough of dungeon runs. Daggerfall, Diablo, Diablo 2, Titanquest, Arx Fatalis, Nox, Dungeon Siege, Dungeon Siege 2, I'll even count World of Warcraft for bloody sake!

And now... well, it seems a shadow of its former self. Where did we go wrong? Why have we been shunned from the light, and why is the only certifiably GREAT dungeon game actually a euro game... Gloomhaven! Even that was nearly 10 years ago now!

So i ask you... what caused this once dominant and glorious genre to lose its shimmer? What made it so dull and redundant like it often is today, full of tropes and hackneyed, tired concepts. Where is the innovation? The sense of mystery? The roguelike levels of replayability we were promised, only to... blow away in the wind like bone dust in an ancient tomb once unearthed to the sunlight...

How did we go wrong? What can we do to restore it? What would make Dungeon Crawling fresh again?
