One day when I was young, my mum came home with two PS1 games which she gave to my brother and me. The first one was an Incredible Hulk game, the second one was the first European King's Field. Apparently, our cousin got nightmares from King's Field. (Can't remember why he didn't want the other game.)
In the beginning I was only watching my older brother play, but after a while I started playing it as well. We both played it like obsessed, and far into the night. Good times. :D
