Sid Meier’s “Civilization V” is just a video game, but it is unbreakable. Most Civilization gamers will warn you, you will lose your job if you are working, or get a bad grade if you are a student, once you start the game.

It’s a turn-based strategy game centered around constructing a selected society into a world power. And, yes, “Civilization V” can look seriously boring to the casual bystander. However, for the person at the helm of the game, each turn can lead to a weighty decision, giving the player a certain feeling of power that few, if any, games can match.

The first thing users will recognize is the interface. Heavily influenced by Civilization Revolution, it’s a thing of minimalist beauty designed to display information clearly and succinctly. It also allows you to feel pride in your developing society on the new-look World Map, which is now a thing of shimmering beauty as a tableau of fields, factories and road networks. Zooming in and out is smoother than before and it makes the game annoyingly easy to keep playing.

If you get lost, the city advisers’ counsel seems more timely and pertinent than before. Not that you need it, as hovering your mouse over, say, your happiness rating quickly reveals exactly why your population is either cheering your success or about to start rioting. It’s not all cosmetic either. “Civilization V” has been rebalanced and structured in all the fourconditions on which victory depends.

Diplomacy, as ever, is the weakest of the bunch, but even this has been improved thanks to the newly evolved City States, which now cherish their independence. As they outnumber other nations, but have no territorial ambitions of their own, they are well worth allying with. They will attack your enemies with blind loyalty whenever called upon.

The biggest change is the military aspect, by replacing the old square-based geometry with a hexagonal one. This means you can now attack enemies from two extra angles, even firing from two or three squares behind with some ranged or progressed units.

However, to compensate, you can no longer stack units in the same place, leading to a more strategic if cumbersome form of combat that “Civilization” fans will either hate to bits or find to be a revelation. How it all plays out online remains to be seen, but “Civilization V” is a hugely accomplished reinvention of a franchise that was showing signs of dotage.
