As with any game that has a new version Civilization 5 has many changes. The rules haves changed slightly in order to make the game flow better and to attempt to increase to fun. In this guide we will show you how to use those changes to your advantage.
One of the new features in Civilization 5 is tile expansion. In the other Civilization’s once your culture hit a certain level, the borders of your town would expand. If no other civilization was around your town, those borders would expand out one square in every direction. This has changed dramatically in Civ 5. Now the tiles are hexagonal, giving a more rounded shape to your area. Also when you expand, it is one tile at a time. This is usually due to culture from the city, but can be purchased as well if you have the gold to do so.
The City States in Civilization 5 is another new concept. The idea here is that there are some smaller countries that will never be a super power. Because they are not in direct competition with you to win the game, the city states are easier to influence and can be used to your advantage. If you are playing nice, you can keep them happy by giving them gold, cheap units and helping them with their enemies. Each type of city state will give you different benefits once they are your ally. The cultured city state gives you extra culture, the maritime extra food in each city, and the militaristic extra troops. They can also give you their extra resources when they are allies.
Social policies are a way to get an edge on your opponents. Be sure at the beginning of playing a game of Civilization 5 the figure out your plan for social policies. For instance if you are playing the Aztecs, an aggressive war style race, you would want to start out your social policies with honor. This would give you and edge on barbarians in combat and more benefits as you put more points into this social tree. The social policy tree gives you different advantages and can change your playing style. Be careful to look ahead though, as some social policies are not compatible with others and will exclude later choices.
Resources in Civilization 5 have also changed from the previous versions of, the bonus tiles such as wheat or cattle still give bonuses on that tile when you use the correct improvement on them. Luxury tiles will still supply your entire culture that luxury, any extra can be traded. The strategic resources such as iron and horses have changed. Each tile will have quantity listed on the tile. This is the number of units that use that resource that can be supported. For instance swordsmen use iron. If you only have two iron available you can only make two swordsmen. If you research another unit such as catapults which also use iron you will not be able to build them until you find and access more iron.
Even if you are playing Ghandi and are trying to be peaceful, barbarians and other states will attack and combat is inevitable. One of the major changes in Civilization 5 is the stack. You can no longer stack units. One combat unit per square is all that is allowed. The good news is that you city now has a decent defense rating and can attack but shooting up to two squares away with no retaliation. Combat still has a random factor in it but there is a rating that shows how well you will do if attacking an enemy. This will give you an educated estimate as to whether or not the fight is worth fighting. Be sure to move as many troops around your enemy as possible as this will give you a flanking bonus. Taking a city will require softening up the city with ranged attacks and then some attacks with melee troops.
Once combat is over and you have taken that city you have to decide what to do with it. If it is a capital city you cannot destroy it. In Civilization 5 taking all the capital cities will win the game as long as you have not lost your capital city that is. Taking a city will lose some of your global happiness, after all we have been calling them the enemy and now you want them to be our friend? You can destroy the city, make it a puppet city or keep it as another city. A puppet city contributes to your empire but you have no control over what it builds. Depending on your strategies, as you take cities you can mix and match your choices as to what to do with the cities you take. Also if it is a city state that was conquered by someone else you can give it back to them and make them very happy.
Since civilization can be played in many ways, my suggestion would be to decide what you want your civilization to focus on and stay focused in that direction. If you are a conqueror, focus on building up your armies and continue to drive the enemy to its knees. If you are a merchant buy up everything you can, including the alliance of the city states. If you try to be the strongest, most cultured, and technologically advanced you will probably fail. Focus on one and the others will follow as you start to defeat your opponents.
