How does Civ V rate with you compared to 2 other top competitors? The following are also turn based strategy games: Hearts of Iron 3 and Europa Universalis 3.
ALL THREE games have a lot of bugs but all three appear to be very enjoyble in spite of all their bugs.
I have only played Civ V among those three and, thus, voted "Cannot render an opinion since never played all 3."
Frankly, I'm thinking of buying one of those others if Civ V doesn't get a big improvement in AI combat strategy in the next 60 days. I may rely on the results of this poll to make my choice. If Civ V wins this poll, I'll stick with it for another year.
