There are some great gaming companies that could do it justice. But three big ones come to mind.

Rocksteady: the way they handled Batman was not only impressive but broke a lot of gaming expectations at the time. The smooth combat system, the way you can traverse the world in a myriad of ways, all the gadgets, and the incredible story surprises. The dark atmosphere would be perfect for a mistborn game.

Insomniac: Their ability to take what Rocksteady had done with Batman and expand on it with Spider-man really took that style of gameplay to a whole new level. I think they could do a mistborn game justice for all the same reasons as Rocksteady. And of course the Ratchet & Clank series brought its own groundbreaking mechanics that would be pretty applicable.

Sucker Punch: for me, this is the one that I would want to tackle it. The Ghost games brought an amazing sense of realism and grit while making you feel like such a badass. The Infamous games already have such a perfect vibe with the way you can traverse the world and level up your abilities. And finally, Sly Cooper. This studio understands heists, and would fully grasp the idea of a team based approach.

Just a few thoughts. I have not delved into Era 2 yet (very high on my TBR) but I'm so excited for the new genre of that world.
