Just finished my first 100 turns.
All very slick (sort of) and all very clinical. Left me feeling a bit cold to be honest.
Maybe it's just all new, but CIV 4 had so much more atmosphere and I felt attached to my cities and units. Here, nothing of the sort.
Maybe it's just the demo talking, and perhaps the full release will grow on me.
It left me feeling the same. There are some elements I like but even the landscape graphics seemed bland, despite being technically pretty. In fact, straight after finishing the demo I wanted to reinstall 4. I hope it grows on me.
