So you're on the fence on deciding weather you'd like to upgrade your World of Warcraft to the Cataclysm with the giant dragon and the fire and the crazy wild awesomeness? Perhaps you'd like to give it a whirl for about 10 days while you think about if you'd like to have it forever? Now you can do just that. Today Battle.net and Blizzard give you a completely free 10 day trial period (similar to some other older games they've still got lying around) during which you can play the game in its fullness. After that, probably you'll be so WoWed that you'll need to Cataclysm your WoW to stay WoWed enough to WoW forever.
