Dice bias
Dice throw results are completely biased, especially on higher levels this becomes an obstacle that ruins the whole gameplay. How its possible that the computer puts two of his starting villages around the resource numbered 3 and he keeps on throwing 3 throughout the rest of the game. Moreover, this applies to other players as well. Typically it doesnt really matter whether you occupied the best "6" or "8" fields. The computer still gets resources one after another. The only "winning" strategy seems to build your settlements next to the computer, because these are the most probable numbers to-be-thrown. Rubbish!
