Microsoft sure know how to market Final Fantasy XIII for their console. To go with todays announcement, Xbox.com is calling all Twitter users to "Retweet" a message for the chance to win an exclusive Xbox Live item for Final Fantasy XIII. We have no idea what the item is but you can bet people will tweet regardless. Here's the message:

Retweet this message to help unlock an exclusive Xbox LIVE item for Final Fantasy XIII #FFXIIIXBOX http://xbox.com/ffxiii

Twitter is a force to be reckoned with when it comes to marketing and it's a good way to get people to advertise for free. If you're one of the people thinking about getting Final Fantasy XIII on Xbox 360, there's no harm in giving it a try.

Also Square Enix has announced their new "Lucky 13 Campaign" where new information will be delivered about Final Fantasy XIII on the 13th of every month until release. Let's hope the wait for that is worth it.
