The angle I forgot to add is that Apple has, in my opinion, destroyed the ecosystem. The race-to-the-bottom they promoted created a situation where a game development team could very well spend a million or more developing and game and have to give it away on a hope and a prayer.
And "hope and prayer" it is because you have to dump even more money into marketing and hope it catches on so that your freemium or in-app-purchases model generates enough cash to recoup your investment and make money.
Not everyone is going to get a hit at the level of "Clash of Clans", yet everyone is now expected to produce stunning graphics, animations and game-play, give it away, create a back-end infrastructure to support hordes of free players and hope the game engages enough to generate revenue thorough IAP or ads.
My guess is one could do better gambling with a million dollars in Vegas than creating a game with that money.
