In over 100 games on small maps, there were about 3 instances where the opponent broke my Gold Mine on turn 2, forcing me to retreat. Of course, I was playing weaker and mostly chose opponents of similar skill. But even in those cases, the game didn't end even on turn 3.
Now, it's true that more often, I give up on connecting roads with the opponent and instead focus on developing the Gold Mine through unpaved roads.
Sorry for the expression, but "crappy Grail" – as soon as they start digging for it every game or almost every game, the AI will shove it somewhere far away. If what I saw with Reddit and Nedved, where both dug for the Grail near their main town, turns out to be a system, then if it's not canceled, everyone will have to learn to dig for the Grail and trade for specific castles. And check for the Obelisk and Grail at my town or the opponent's. Whoever digs it up faster is the winner.
Nedved isn't an experienced student of Reddit; Reddit has always played that way, starting with trading and so on.
