Looks like you know a lot about F2P games, can you help me understand this fee in the context of other variables such as cost of customer acquisition? Is that usually a much lower amount than 20 cents? What about 2 cents, which would be the cost on a pro license, which most successful F2P devs would assuredly be able to afford?

I’m hoping you can answer these with concrete data. If that’s not possible, could you share your references?
