Citadel Studios attempted something unusual on Kickstarter recently by pitting backers pulled from the Twitch channel against one another in a fight for extra rewards. They've also announced the opening of their official Shards Online forums.
Details about the Battle of the Backers can be found on Citadel Studios' official website.
