The accelerometer-powered, tilt-sensing title was sold for $9.99 on the App Store, Apple's digital distribution platform for iPhone and iPod Touch software downloads. The game amounted to over 10% of the App Store's total software sales in the month since its launch, which totaled about $30 million.
"That's a substantial business," said Sega of America president Simon Jeffery. "It gives iPhone a justifiable claim to being a viable gaming platform."
Apple CEO Steve Jobs also revealed that the App Store totaled more than 60 million downloads in the same period, though most of those were free downloads. Jobs expressed his enthusiasm for the burgeoning market, expecting that sales would remain brisk.
"This thing's going to crest a half a billion [in yearly sales], soon," Jobs said. "Who knows, maybe it will be a $1 billion marketplace at some point in time."
Apple retains 30% of the proceeds from App Store software revenue to cover transaction fees and other operating costs. Developers, meanwhile, keep the remaining 70%.
Numerous games already available on the App Store, including a version of Vicarious Visions' Crash Nitro Kart and Hudson's Bomberman series. An iPhone edition of EA's life-sim Spore is currently planned for release next month, along with the 3D action adventure title Krull, developed by Digital Legends Entertainment.
