So, I've seen quite a few post-mortems of freemium games, but I haven't seen any data of low-level success stories. Everyone knows how much money Supercell with Friends make, yet no word about games between those two ends. Are there any shades of gray in freemium business at all?
I haven't found any data on this either, and I wish it existed. As you go down the rankings on the app store though, it gets harder and harder to get sales numbers.
