Here are the steps, to writing a great, cliched Gaming Creepypasta!
1.Have the characters act like Complete buffoons!
2.Make Light-hearted/innocent things "Horrifying".
3. Have The Monsters in the story "Bend the laws of physics"(EX; Jump Out of Computer Screens)
4.Have the games Cartidge/Disc written with a black marker, along with a message from the sender.
5. My advice ends here...Just go Copy Sonic E.X.E and a bunch-of-other-rejected Pastas, criticized for their......Ya Know.
