EA Sports launched World Series Superstars yesterday as its latest Facebook game offering, after successfully releasing Madden NFL Superstars and EA Sports PGA Tour Golf Challenge and FIFA Superstars on the social networking site.

EA Sports began getting into social games after it acquired social game creator Playfish Games two years ago. The Madden NFL and the FIFA franchises draw in 1.5 and 3.5 million users a month respectively, says Gamasutra.  This is EA’s first return to Major League Baseball since MVP Baseball 2005,when it lost the rights to MLB to 2K Sports.

World Series Superstars allows players to build and manage major leaguers using free to play virtual cash or buying $20 or $40 player packs. “We are delighted to be back (in baseball),” says EA Sports president Peter Moore, according to USA Today. “It takes the best of what we started with FIFA and iterated now with Madden. And now with baseball, it continues to build upon all of the things consumers have liked about the games we have out now. And I can’t think of a game that is more suited for this type of game mechanic than baseball.”

Players will have to train their teams so they can make the majors, “Whether it’s pitching, batting, infield, outfield, catching fly balls, picking up ground balls, all the core elements of baseball, your team is constantly training and as you train you get better and you win more games and you get more points,” explains Moore. “Baseball is much more uniquely focused on the GM element. It’s very different from FIFA where you have the same 11 players playing each game. You are much more in control in this.”

Social gaming is becoming a multi-billion dollar industry, and many companies are looking to get a slice of the pie. Social games are not only increasingly popular but cost millions less to make than console games. The largest social games maker, Zynga, has an estimated market share of $5.5 billion, reports CNBC.

“We’re pleased to see EA Sports bring the excitement of baseball to the 200 million people who play games on Facebook, and make it easy for them to share the experience with their friends,” said Katie Mitic, Director of Platform and Mobile Marketing at Facebook in a press release.
