Reynolds has worked on several great titles during his career. Civilization II, Alpha Centauri, Rise of Nations, and Frontierville are among them. After leaving Zynga in 2013, he revived Big Huge Games (which developed Rise of Nations) as SecretNewCo to create the mobile combat strategy game DomiNations. SecretNewCo took the Big Huge Games name back in 2013, when the state of Rhode Island auctioned off the rights. Big Huge Games was acquired by South Korean game developer Nexon in 2016.
