Kolb and the Dragon is a choose your own adventure book. Big deal you say, and rightly so. But Kolb and the Dragon is a choose your own adventure book inside Skyrim. Yo dawg.
I might be super late to this, this might be old news, but I was not aware until this point that Skyrim had a bloody choose your own adventure book within its own game. That is pretty incredible. You can check the whole thing out here.
It got me thinking of those moments in video games — moments when you realise or notice something amazing after hours of play. The one that immediately springs to mind is in Metal Gear Solid 4: Snake's stress meter would increase when he spent too much time in the sun, and then reduce if he found shade. It took me three playthroughs to notice that. Mind blown.
Dark Souls has a number of insane details as well, particularly in its embedded lore. If you kill Gwynevere, Princess of Sunlight, the entirety of Anor Londo becomes dark. That's insane.
Then there's the whole Trials riddle. I've always loved hidden details like that in games.
