If you listen carefully or wear headphones you can hear you character breathing
Laughed my ass off the first time I realized this was my character breathing, and not an enemy. I spent 75% of my first playthrough hearing that noise and expecting a black knight right around the corner or something.
Might be pretty late, but I JUST noticed you could LEAVE the white fog on your first encounter with Seath...
Anything else that took you an embarrassing long time to notice?
The most embarassing thing was finally stumbling upon the Partizan in the forest in that little nook. I was so blown away when I first saw it in some random video. Of course I barely ever used the weapon but still.
This, I never knew about that until way later. I also never noticed any of the 2 headed tree snakes until the one guarding the partizan.
