Three weeks ago IGN reviewed EA's latest Battlefield game, Battlefield Heroes. This free-to-play, browser game offers players a chance to refight the battles of World War 2 in more light-hearted, cartoonish format than the series has seen so far. Since the game is played online on EA's servers and relies on player-purchased vanity clothing items and advancement widgets, the development team keeps a close eye on player performance and preferences. To help learn more about how players are playing Battlefield Heroes, IGN spoke with senior e-commerce analytics manager Rommy Ghaly.
