From
Gauntlet:
"Wizard needs food badly"
"Elf shot the food"Just about anything from Monkey Island.
From Spaceward Ho!:
"Yeeeee-hah!"
"Much obliged..."
From Marathon:
"Frog blast the vent core!"
"Shoot somebody else, ok?"
In Sinistar, which was one of the scariest games till Doom, I think it was actually, "I hunger", then "Run, coward!" And then the thing would come sweeping in at you, laughing menacingly. The coolest thing about that game was how good it was at making you feel you were playing in a world that extended WAY beyond the edges of the screen.
