Ladies and gentlemen, Galactic Civilizations 23.
We can all hope...
But in all seriousness, I have an idea for a few other metrics to spice up the ethics system beyond just "good" and "evil". Of course, if ALL of these were included, the game would be nightmarishly complex, but some of them might add a little variety.
Scientific (research and engineering bonuses) vs. spiritual (morale, luck, and other random bonuses)
Capitalistic (econ) vs. socialistic (production)
Collectivist (mfg. & soldiering) vs. Individualist (research, creativity, etc.)
Idealistic (morale, soldiering, courage, etc.) vs. pragmatic (logistics, science, mfg.)
active (military, courage, creativity) vs. manipulative (diplo, influence, logistics)
These would not only change bonuses, but also how the AI behaves and how other civs interact with yours. You could change the values through ethical events, diplomatic deals, even techs and imps. Needs soke more work, but I think I could go somewhere with this!
