“Initial price” seems to be the lure. Game revenue would look a lot different if publishers were required to use the term “Submit DOWN PAYMENT of $0.99 (All Content: $200.00)” or “Pay First Month $0.99 (Price Per Month: $3.99)” or “Try Now (All Content: $389.00)” or “Buy Chapters 1-3 ($9.99)”.
Similarly, it would be very useful if publishers were required to show statistics on what percentage of people bought each downloadable pack. If you offer different downloadable chapters for instance and I see you have 50,000 downloads of the first chapter at $0.99 and like 10 people buying Chapter 2, I can conclude that maybe your game was not fun enough for people to want to play more. The platform may be able to determine this too, e.g. calculating an “average price per hour” factor that translates app time from those who purchased at least one component of the app, giving you a sense of how much time they were able to spend for their money.
