Parallel Kingdom, with his co-founder and a staff of seven in Madison, Wisconsin, surviving on $20,000 of savings from a stint at Microsoft. Today, PerBlue generates $3 million a year, supports 35 employees and has successfully launched three free-to-play MMOs in the Parallel universe on Android and iOS.
PerBlue's Parallel Mafia and Parallel Zombies both hit mobile devices in 2012, but during his talk at GDC Europe, Beck discussed the specific finances of Parallel Kingdom, which has been live since 2008.
Parallel Kingdom doesn't have a massive number of players, hype or notoriety in the wider gaming world, but it proves that when managed efficiently, a mobile game can provide huge profit for a small developer. Parallel Kingdom has 1.5 million registered accounts, but only 15,000 daily active users, which Beck admits is "not that big." These users, however, represent $0.40 - $0.50 per user, per day for PerBlue. Extrapolated to 50,000 monthly active users, that's more than $200,000 each month in microtransactions from one title alone.
