Re: Realistic ways to screw up you empire
Build only cultural buildings and never upgrade the military ones. Set taxes to VH and leave a small garrison - that would cause the cities to rebel. Make an alliance and then attack that faction. Load your stacks onto ships and then send them into battle with every other navy you can find. Build stacks of wildly inappropriate troops and attack stacks you will always lose to - like lots of onagers and ballistas against a stack of HA? Send stacks off to attack wildly remote areas and then send the navy that transported them on a suicide mission. I would have thought it would be quite easy to ruin your empire very quickly?
