I would like to see Approval / Morale play a slightly larger role; currently, it is almost counter-intuitive that it does NOT play a role in determining cultural defections, insubordinations, or rebellions. I think it would be both cool and exciting for fun game-play if there were some kind of algorithm which increased the rate at which foreign IP affected planets which dropped below a certain Approval rating, asymptotically increasing as Morale approaches 0.
