From the Kickstarter Update...
This is David, the project manager for Magnum Opus. As many of you have noticed, the rulebook does not include the list of backer names I promised in the pledge levels. There's no excuse and no reason, it just didn't get done and it's my fault. A project manager is there to make sure everything is right and I failed. I deeply appreciate and respect all of the backers who make our projects possible and my failure in this task is heartbreaking to me, personally. I am truly sorry and offer my apologies to the game's designer, Ian Stedman, and to each and every backer.
We launched our new website a few days ago and as soon as the webmaster is done hammering down the loose edges, I'll get an appreciation post added to the Magnum Opus game page listing all the backers who made this wonderful game possible.
