I also found the game enjoyable.
It has this addictive quality that makes you keep pressing end turn and/or discovering that it suddenly 2:00 AM and you need to be awake for work in five hours
Kinda like MOO2 had but Galciv didn't. The turns flow more smoothly than even dominions.
Yes, its an enjoyable game. One I'd really like to see expanded to explore other areas of human history: like rise and fall of Rome, colonialist europe and much more.
