Summary: This is a great game once it is up and running. If you don't have a techie in the family do not buy this game. It is not plug and play. Needs some serious work to get it going. Once it is running it turns out to be a really enjoyable experience. Steep learning curve, but worth investing the time. Save your game regularly as the program crashes once and awhile.
Summary: I've been playing Civilization games since CIV III, and have probably played this series longer than any other game even if you combine all their play times together. But, unfortunately, with my updating to Windows 8.1, and no patch, I find getting passed turn 140 or so impossible, even if I use the compatibility settings. But, with a patch I expect to log in more hours. Until then though, I would recommend keeping with your Windows 7 or 8 to play this.
Summary: The Brave New World upgrade of Civ 5 makes an already good game even better. It is easier to play but still retains all the strategic and tactical refinements that allow a thoughtful player to wage a superior campaign. The best Civilization game ever.
Summary: Plays well overall ,but I wish the Civil War game was more authentic. No need to have cities "defend" and the constant fighting is not necessary. Leaves no time for maneuvering. If there are no friendly forces adjacent to a city, it should just be "captured without a fight". Washington and Richmond would be the only exception.
Pros: Have played every version of Civ and Civ 5 is fun, there is alot of additional DLC if you want to get extra civilizations, more rules, units etc. This is only the plain vanilla version but still great game. Code came within 30 minutes.
