The only resource with a large difference in win percentage is wheat.
Knowing that starting with four out of the five resources doesn’t significantly decrease our chance to win, is there a resource that we should prioritize with starting settlements? The only resource with a large difference in win percentage is wheat. The players who started without wheat won less than 10% of their games (compared to the expected 25%). Starting without sheep may also put you at a disadvantage while lumber and clay seem to be the resources to ditch when in doubt.
