I have always had trouble with happiness. Now, it is rediculous. Barbarians at -10, then they blow up all my luxury resources and it just goes down hill from there. I was expanding well beggining/mid-game and taking over the neighboring civs. I only have the game on normal difficult, and I used to play on the higher ones. Besides playing the new civs that deal with happiness better, any ideas on what might be done to increase it?
