First time poster etc. Hello everyone 
What is the greatest challenge one can face and still emerge victorious?
I ask because I completed an interesting game yesterday. It was hard, but not even close to impossible as I would have almost hoped.
I won't tell you the settings I used just yet, first I'd like to know what people would consider the ultimate civ V test of ability. Obviously it has to be something that is possible, but ideally it would be something that is only doable by the very best player ever to play the game. What I would like to know is how far do you think the difficulty can be increased until nobody can complete the challenge. After we reach a consensus we can take a tiny step back to barely, marginally, theoretically beatable settings and enjoy the result (like this:
).
