Looking at the gameplay vids, I kept getting Call to Power vibrations. Not just because of the separate 'battle scene' (which, amazingly, Millennia manages to do even worse than CtP did 25 years ago!), but because CtP was the first Civish game I played that I felt had so many good ideas in it that were all, almost without exception, badly implemented.
If history repeats itself, note that CtP was ranked the 16th best-selling computer game of 1999 and was nominated for "Most Disappointing Game of the Year" - not exactly the sort of accomplishments to shoot for . . .
