After the success of the first two BioShock games, the team at 2K Marin had several concepts for what could be the studio's next release. One of them sounds fascinating, because it would've been an attempt at a Destiny-like project several years before Bungie's own shared-world shooter came out.
On BlueSky, David Lindsey Pittman, a programmer on BioShock who worked at 2K Marin, spoke a little about what was known as Project Richmond. "Imagine: the team that made BioShock 2 made Destiny before Destiny existed," he says in the thread.
