Thanks :) Yep, at first I thought about just "killing" them but that was boring so I gave them "money" and when they loose all money they keep rolling a dice till they turn :). There is also a city wealth display but since it didn't do anything I deactivated it.
Emergency situation is a great idea - I originally intended a jail break scenario but couldn't really find a good condition for it and then I went out of time :( . Maybe I could use the wealth display or something like "if the cop is away from prison too long there is a chance prisoners escape"
Thanks for your feedback!
