I don't mind games like Spelunk having ancient traps which are functional despite the lack of a maintenance crew to keep it going. It's a game and sometimes you want to use ancient civilizations as a flavorful setting without regard for logic. Ancient arrow trap goes FWIP!

But sometimes a game tries to be more grounded, more realistic and seeing all those century olds machines just waiting for the protagonist to arrive and pull a lever and everything just works always irked me a bit. Ancient stone elevators in particular are a pet peeve of mine.
