Facebook is making a concerted effort to target core gamers this year.
"You'll see a whole set of games hitting in the next two quarters in particular and throughout the year that really start to redefine what people think of Facebook games," Sean Ryan, head of game partnerships at Facebook, told Reuters.
While it's best known for family-friendly social titles, Facebook plans to embrace "more core player-versus-player games" in the shooter, role playing and strategy genres.
"It doesn't mean we're walking away from other games, but there's no question our focus for 2013 much of it will be about becoming a better platform for core gamers and developers who make those games," said Ryan.
To do so Facebook says it has been investing time and resources on a number of high-quality third party games - and it plans to launch ten such products in 2013. These include u4iA's FPS Offensive Combat, Plaruim's RTS game Stormfall: Age of War, and nWay's RPG ChronoBlade.
nWay chief creative officer Dave Jones, who's credited with the creation Grand Theft Auto and Lemmings, said Facebook needs a defining game that establishes it as a legitimate platform for core games.
"Like Super Mario did for Nintendo or Halo on Microsoft, I think it just takes one title to come along, sort of as a benchmark to legitimize the whole thing," he said.
