As revealed to The Verge , Ouya CEO Julie Uhrman thinks this is nothing to worry about for a free-to-play console. Ouya's point of difference is its 'try before you buy' model, and while only 8 percent of gamers have upgraded to the paid versions of its 20 top grossing games, Uhrman stresses that a lot of social and mobile app developers "would kill" for an 8 percent attach rate on a brand new platform."These numbers will grow as more gamers pick up consoles, and as we attract more developers, and I believe that by the end of the year, we'll see a few developers telling us they've made more than a million dollars on Ouya."Currently, the biggest "hit" on the console is TowerFall from developer Matt Thorson, which has generated a total of $21,000 after Ouya takes its cut. Uhrman says this is a relatively healthy figure for a title on a new console."To say developers can't make money on Ouya — I take offense to that. I'm sure the creators of TowerFall and Hidden in Plain Sight would take offense to that. The console has only been out for a month, and developers have only had access to the hardware for about 6 months. We really like what we see so far, and so do developers and gamers."You can read our breakdown of Ouya's early sales figures here. Lucy O'Brien is Entertainment Editor at IGN AU.
