Okay, this civilian count is a terrible idea.
Phylanx is supposedly the only organization fighting the aliens, but if we lose a few civies they will shut us down so... who?.. will takover? It doesn't make sense. The aliens are attacking, and we are going to lose people and the only way to survive is to keep fighting them. The score made sense in the original XCOM because if we're doing good in one country, then the other countries might get a bit ticked if we don't help them as well. This is an artificial limit that just doesn't work. Game over should be based on our no longer being able to sustain ourselves and being attacked by the Aliens, not just, "Oh well, we lost a few people. The people of Earth accept our alien overlords and freely take the death they give us without a fight".
From a gameplay perspective, if Civies are going to cause me to lose the game, then there better be some decent AI behind them. They better actively try to get to safety, and not run straight into the enemy and get blasted. They should also be able to pick up a knife and try to fight or something.
I love what you guys have done with the game and greatly appreciate the whole effort, but this idea needs rethinking. This kind of artificial limit is something that would stop me from recommending this to anyone else because new people just will not be able to adapt to that. At the very least, this number should be in the hundreds and have some kind of decay on it as has been suggested.
