Finnish developer Supercell (Zombies Online), which builds core-targeted social games, has adopted a "Tablet-First" strategy, and is now building its projects with tablet computers as their lead platforms. The studio believes tablets are becoming the platform of choice for gamers, which is why the company is shifting its focus away from online titles -- less than a year ago, Supercell raised $12 million from investors to work on browser-based social games that appealed to core players. "The unique confluence of technology, interface, mobility, and social packed inside these magical devices opens up brand new opportunities to create rich gameplay experiences designed specifically for the platform," says Supercell CEO Ilkka Paananen. This announcement comes just a few days before Apple is set to hold a press event where it's likely to announce the iPad 3, its latest tablet computer model. Supercell also plans to show off its first tablet title, Battle Buddies, at the Game Developers Conference next week. Supercell has also revealed that it's appointed game industry veteran Greg Harper as general manager for its North American operations. Harper was previously president at social game developer iWin, and business development VP at casual game portal Pogo.com (now owned by Electronic Arts).
