This example was given in the context: "Dave was very close."
Dave was indeed very close, but only close to the Grail.
The Grail was buried right at the entrance to Dave's starting town, just one step away.
And the game ended with Reddy running across the entire map and starting to dig up the Grail right under Dave's nose; he was just one dig away when the final turn occurred.
So, resistance had nothing to do with it here.
