Choosing your leaders and their advisors is vital to your success. They supply you with information and opinions and deal with the complaints of your clan and other clans. Some leaders have better skills than others, but that is not the only attribute you have to use for your decision. You have to consider what god they worship and what their specialities are, attributes that also effect their leadership abilities. The choices you make have an effect on everything about the game.
Some choices only have immediate consequences and others have long term effects.
One bad choice can destroy everything your clan has fought so hard to build. Then on the other hand, a good choice can bring wealth, peace, or prosperity. I think the battle determinations could have been done a little better, because your strengths sometimes seem to have no noticeable effect on the outcome of battles. I have often lost battles in which my forces were much better prepared and led than the opposing force. I enjoyed the game immediately.
