Do you remember, especially during childhood, that you were scared about anything in any PC game, and may even feared to play it?
I remember, that Harry Potter 1 PC, I was scared, when I had to escape from Filch at night in library.
In Harry Potter II PS2, I was scared, when I had to go in magical menagerie, and the shopkeeper was chasing me.
Then I played some Czech freeware game, that when I lost the game, symbols of the game turned into skulls, and I was scared very much by it.
I vaguely remember, that in Commander Keen, on windows 98, I was scared of some monsters in the game.
Last thing, that I can remember now is, that in The Sims 2, when a person died, I was scared of the Grim Reaper, when it appeared.
