I wonder if they will create a gallery containing all the creations. Hell done correctly they could set up a meta event on top of the event. Have the community go through them select a sampling of the best of the best. then have some of the developers pick out there top 10 from that group.

Winners could get an in game item or a load stone history badge. And seems its all copyrighted by square the super grand prize winner could get there creation used as part of xiv advertisement or something. Now that would be one hell of an event and a prize. just think about it, your characters mug on promotional material. Beyond epic.
