It's always interesting to see just how some games would function if you just... do nothing. Indeed, one of the most famous examples is the Metal Man boss in Mega Man 2. If you simply leave the controller alone upon entering the boss room, your opponent will do nothing until you make the first move; step forward just an inch and Metal Man will instantly start flinging his blades toward you.
In a similar case, as pointed out by Twitter user Supper Mario Broth, the mine section within Super Mario RPG will actually play itself if you don't press any input upon commencing the sequence, completing the whole mini-game in a total of 3 minutes and 24 seconds. So that means you can pop the controller down, stick the kettle on, make yourself a nice cup of tea, and come back just in time for the mini-game to complete itself, no bother.
Of course, you'd have to question why someone would want to complete a particular section of a game without actually playing it, and indeed how such a feat was discovered in the first place. Heck, maybe someone did go off to pop the kettle on at just the right time!
Still, it's a neat discovery regardless, and we're inching to know whether there are any other examples of it, particularly within more modern games. Could it be possible to complete a mine cart section in Donkey Kong Country: Tropical Freeze without doing anything? Somehow, we doubt it.
What do you think of this little discovery in Super Mario RPG? Is this the first you've seen of it, or have you known for some time? Let us know!
