Sleeves. Some games get played. Great games get played a lot. A board game will start to show its wear over time, but an excellent way to keep them from aging so quickly is to sleeve the cards that come in the set. Not sure what size to get? Fantasy Flight marks the back of their boxes so you know exactly what size and how many you need! Just check the back of the box the next time you play. Say you're looking for instructions or something. In addition to protecting those cards, they can be used to add a little flair to the game by introducing art sleeves, like the ones above. A load of different card sleeves can be picked up at Cool Stuff Inc for $1-5 a pack based on quality and art.
