Carcassonne is a boardgame that is different every time you play it. You start with one tile in the middle of the playing area and then on your turn you turn over a tile and place it. you have to place the tile appropriately. For example you have to have the roads going the same way. You build your map this way. You build roads, farms, cities. You have markers you place in these areas as you build your map. You can't place a marker if somebody else is already there. So you have to find a back way in to their city to share the victory points or you can take over the city if you can place more markers than your opponent. You also score points for having farmers in the fields and finishing roads.
This game took a little longer than some to understand but once you get the hang of it you will play it over and over. Every game is different as you build the map different everytime. There are also expansions that are available to add the gameplay.
I highly recommend Carcassonne!
