Turbine's Step-by-Step Playbook for Hybrid Casual Development.

  1. Find talented dev team in India, Turkey, Ukraine, Malaysia, Romania or Poland.
  2. Build 'core gameplay prototypes' in service of core gameplay ads, until you find < $1 CPI in US iOS FB.
  3. Assume you will repeat #2 many, many times. If you can produce ads without prototypes, all the better.
  4. Commit to one (or more) of the six proven IAP econ structures most appropriate for your core GP.
  5. Prove D1 retention with 30m gameplay (Tier2-3 Geos, aOS) of 35%.
  6. Prove D7 retention with 120m gameplay (Tier 2-3 Geos, aOS) of 15%.
  7. Implement RVs, Interstitials, basic IAP, HC sinks as per econ model in #4.
  8. Optimize for D7 payback of 50%, D30 of 100%.
  9. Assume you need to attempt the above 3-5 times, while building expertise and a library of reusable systems, before finding your first scalable product.
  10. Once you find it, source as much help, muscle, expertise, liquidity, unfair advantage as you can to retain first mover advantage vs. the inevitable fast-follows.

Good luck!
