When I was young and had a super nintendo I loved playing Super Mario RPG.
I’m playing the remake and I’m at the scene after defeating Valentina. Mallow goes into the castle and Mario was left standing outside.
Back then I didn’t know why Mario pulled out an umbrella and it rained. I just realised after 20 years of playing the original that Mario knew it was going to rain because whenever Mallow cries it rains; Mario knew that Mallow would get all emotional when meeting his parents for the first time.
Blew my mind.
Whiskey Hotel in Modern Warfare 2. When I was a child, I thought we were advancing our way through Russian forces into literal a hotel named Whiskey Hotel. As a young adult, playing the same mission again, I realised Whiskey Hotel is actually NATO phonetic alphabet for White House. I was dumbfounded.
