The Cosmere is a fictional universe created by author Brandon Sanderson in which multiple series and stand-alone novels he has created are all intertwined. The most notable series are The Stormlight Archive and Mistborn. If you read fantasy books, you've surely read or heard of Sanderson. If you have not, then you are missing out and you must live under a rock. To get a sense of Sanderson's popularity, he recently destroyed kickstarters records for the largest funded project where he also funded every other book project out there.
So for those of you that have read these books, would you want a game based on the overall universe?
Me, yeah I would love a large open game where you can planet hop and interact with Hoid and other core characters. Utilizing the various and highly inventive magic systems to either work through core story elements or a fully new story.
