I spent man-years playing CIV III several years ago and never "got" CIV IV with its small maps and cartoon-like graphics. That said, having installed CIV III via the Steam version on Windows 8.1, my version hangs whenever the spaceship screen is run. I am very computer-savvy but despite weeks of trawling bulletin boards, I cannot get past this. Steam or Windows 8 ? Nobody knows and I have lost the will to solve it.
