Yeah on second thought it's maybe a bit more vivid than intended, but it fits what I think is going to happen. Below the top 1-2% of mobile games, it's one big pile of endlessly recycled advertising money. Spend a million in ads, make $800k in ads and $500k in microtransactions, and the $300k is where you have to pay everything else from. Unity is about to bite into that hard and doesn't care if it leaves behind some wounds.
