i would love a quest where someone is killed and you have to find out who did it. by following clues and interviewing suspects
it would be even better if who the actual killer was is left ambiguous. like you can accuse any of the suspects and the one you accused is punished, but the game never actually specifies who did it.
therefore its all up to who you believe did it. everyone who plays may have different opinions on who did it and why they did it. it would be fun to argue on the forums about who actually did it.
