My biggest hurdle is my economy.
I start off fine.. and im usually leading or in the top few civs by mid game, but in the end game im just getting blown out of the water.
One of my biggest issues I think is morale. If a planet's pop gets above 10-11b.. my morale just plummets.
I usually have one "morale boosting building" per farm.. but have sometimes put 2 per farm (though only on really large planets.
Can anyone give me some tips on how to get my economy working well enough to actually finish a big game?
