I've noticed this thread on the MTW Forum, but I don't think I've seen it here (apologies if it already exists). But what rules do you set yourself, i.e. are there some bugs that you've noticed but don't exploit?

The one rule i've adopted is very simple:

"I don't do anything that wouldn't be done in 'real' life'." So for example, I never let a town rebel just to gain exp/reduce population. Indeed, I spend a lot of energy preventing rebellions, as in history no governor would be allowed to encourage rebellion in his own province!

I would be interested to know what other people think and what other rules or checks they put on themselves?
