Food for thought: ONLY ~*0.29% of mobile games make >$1M in annual IAP revenue.

To me this means

  1. Assume you WILL need both IAP+AD rev streams, and
  2. Prove your KPI are top-1% material as early in production as possible.

*(2900 games w/ >$1M in iOS+aOS IAP rev over past 12 months. 1.01M active games on the App Store (iOS) per PocketGamer)
