How can you tell whether a game with IAPs has "good" IAPs -- and the critical path of the game remains free -- or "bad" IAPs, paywalls/gating/pay-to-win? Also, how do you decide whether a content gate is a "bad" IAP or a "good" one?
I'm coming at it from a value-for-money angle at the moment, but I've learnt that people's definitions of "value" vary wildly. Some folks are more than happy to boast about completing Candy Crush without giving a cent to the developer.
