If OpenFeint's lightweight social connections and leaderboards lack the competitive edge your inner hardcore gamer craves, maybe Major League Gaming's latest mouthful will satiate your demands for satisfaction. The Xperia Mobile Gaming Arena presented by Sony Mobile (we told you it was a mouthful) hopes to give smartphone toting gamers a serious cross-platform battleground, offering iOS and Android users competitive leaderboards and up to $10,000 in prizes. Currently the smartphone gaming platform only supports Gameloft's Modern Combat 3: Fallen Nation, but MLG hopes to enlist more competitive titles in the coming months. "The MLG community thrives on competition," explains Major League Gaming CEO Sundance DiGiovanni, "with our new mobile platform, we are now enabling gamers to engage in competitive play no matter where they are."
