The dice rolls are not fair like others mention. What I also see is the game "helping" you out in single player in the worst way: Early game, you tend to land on properties you already bought the previous round. Obviously, you want to land on unclaimed properties, to have first pick on buying them or not. Meanwhile, the AI buys more properties, and so the single player can really only trade. This game may only be fun in Play and Pass mode, haven't tried it yet.
