Obsidian's newest RPG, Tyranny is set in a world where evil already won. It's up to you whether you want to embrace this or spend time making the world a better place. They've said a big focus for this game is making the world react to the choices you make in meaningful ways, enhancing the weight of your decisions and creating a world that is uniquely yours as you leave your imprint on it while you play.
I'm an unabashed fanboy of this studio and Pillars of Eternity was great, so it's good to see them working on what seems to be an even more ambitious project that's already piqued my interest quite a bit. No release info yet but given the genre it's a fair assumption the game will be out on PC only, as was the case with Pillars.
