Pillars of Eternity and Fallout: New Vegas developers, Obsidian, has made the decision to push back the release date for their squeal to critically acclaimed Pillars of Eternity, Pillars of Eternity 2: Deadfire.
Obsidian has stated the Deadfire will be far larger than Pillars of Eternity and has made this big decision due to that fact. I am sure not that Obsidian is taking the time to work more on the game so that it will come out as everyone's expecting.
