Yes, yes, yes, and yes to all. Moral conceptualization extends far beyond what we could ever hope to cover in a forum thread. Thousands of years have been spent trying to come to grips with this notoriously slippery subject. The best that GC2 could ever hope to attain is some distilled, synthetic representation of this concept. But I digress into esoteric philosphy. Back to the subject:
Quite some time ago, I reconciled the fact that I have neither the time nor inclination to attain GalCiv high-ranking bragging rights. I just to play a game that makes me really
think about the choices I make and
care about whether they'll move me in the right direction, that is, toward a win. So sometimes I get to test myself and my skill by trying other's strategies or even think of new ways on my own.
Whether X alignment should have more Y widgets, while Z race should always be W alignment appears more a matter of personal taste and I don't see where that is easily reconciled within a solid game design. These choices are all very nuanced and contain endless shades of gray, uh...kinda like life except with a "do-over" button.

That's why I like these games. They're not about the "twitch" factor (my youthful reflexes are long gone) or fragging online avatars, but about asking questions like these and learning how they play out in a fantasy realm.
So, test yourself. Step out of your Neutrality Centers and Temples of Righteousness and see how it feels squish all who oppose your "correct" way of life... or vice versa.
