On shooters:
Doom:
"You come across a door. It says YOU NEED THE BLUE KEY. So you find the blue key."
Modern FPS:
"John Stalvern follows his objective marker to the Blue Door. He gets a call from Joson (v. Steven Jay Blum) informing him that the Blue Door is locked and to go to Security Control, and that he must fight the demons. He follows a magical marker which appears in his HUD to tell him where Security Control is, only to find that the console has no Blue Key! Gasp!"
"Joson calls him again and informs him that there's a spare key in Engineering (though the Warehouse) and a magical marker appears. Stalvern Fights the Demons and gets to Engineering across a bridge, which promptly explodes. Joson tells him there's a way up through The Vents and a helpful marker appears telling John that he can't walk through the enormous pit of fire in front of him. John makes his way through the vents, coming out through a ground-level grate ten feet from Security Control."
"But Gasp! The Cyber-Demon attacks and John drops the Blue Key in a cutscene! Joson tells him to go to the Blue Door where, behind some glass, a Programmer Self-Insert works on a console while some monsters bash on the door behind him. He BRAVELY opens the Blue Door just before the monsters kill him with an attack they don't have. John continues, wondering why he's even in this game."
