Epic's Infinity Blade debuted on the App Store less than a week ago, but it has already become one of the most successful app launches of all time, reportedly grossing over $1.6 million in its first four days on the market.
The estimate comes from Appmodo, who noticed over 271,000 Game Center users registered with the game, and with the game selling for $5.99, the total works out to over $1.6 million in revenue, of which Epic receives 70% while Apple keeps 30%. The totals appear to be even higher than those estimates, however, as Epic's Mark Rein tweeted that actual sales are actually quite bit higher than that suggested from Game Center stats, noting that not every iOS user is on Game Center.
