What a nice Review! Thank you so much for your Comment =)
I love to discuss these kind of things. You mentioned the Cops AI being unpredictable, which is not entirely the case. You can predict their movement direction indicated by the light cone. Also, when they reach their destination and change their path, they will give you a short time to react on the new situation, as they will stop, look around, then continue with the new path. So, true, they are not entirely predictable, but they behave in a way that makes stealth and sneaking a good strategy, besides the obvious “run” strategy.
Thanks again, comments like yours make my day :D
