With a time limit of only 15 minutes, it'd be easy to assume that there wasn't much to this pre-order bonus but the sheer wealth of challenges and unlockables means it's a very easy game to get wrapped up in. A cursory glance at the internet demonstrates just how much players are talking about this small piece of DLC, desperate to figure out the best way to accomplish certain goals. From a business point of view, it's a fascinating way of encouraging hype for a title but one that I strongly hope will become more common.
