Electronic Arts’ follow-up to runaway Facebook hit The Sims Social, Risk: Factions, launches today on the social network.

The game faces a two-front battle in trying capture a dedicated niche audience while also keeping up EA’s momentum in the social games space.

Despite being named after a board game like EA’sMonopoly Millionaires, Risk: Factions actually has more in common with The Sims Social as it’s based on an existing video game franchise.

The original Risk: Factions is a downloadable title for Xbox Live and PlayStation Network where players choose one of several “factions” and play against other players or computer-controlled opponents in the classic turn-based strategy game of Risk, which has players attempting to take over an entire world map.

In making the jump to social, EA has adapted the title for speedier play and more engaging multiplayer. Aside from the usual social game “hooks,” such as harvesting resources or matching games for bonus items, the developer has also added features and factions to create what amounts to an entirely new game experience under the same franchise.
