I will be adding a per planet 'happiness index' fairly soon as well, which will take into account things like new construction, foreign trade, etc etc.
New way to wage war: stop all trades with your neighbour. Not just your own, but convince (or force) their neighbours to stop trading too, meaning happiness slowly drops and "insert bad thing" happens! Definitely makes having a larger empire hard to do
EDIT: Did anyone else not get a turn report today?
