GameFly's Unlimited PC Play program has expanded today. Members that missed out on BioShock, Civilization IV or X-Com: Enforcer, can now play them as part of a paid GameFly membership.

As part of a new deal with 2K Games, GameFly has added the three classic games to its Unlimited PC Play library. Members can play as many games from the Unlimited PC Play library as part of their subscription.

2K's rationale for offering the free games was simple: Introduce gamers to a series they may not have tried, especially with BioShock Infinite, Civilization V: Gods & Kings and XCOM: Enemy Unknown expected to hit shelves this year.
