In-app purchases (IAPs) are the primary monetization strategy for many free-to-play gaming apps. IAPs offer significant revenue generation at a low cost, both in terms of resources and player experience. But relying solely, or even mostly, on IAPs has trade-offs that could affect the long-term success of your game.That’s why Unity’s Game Design & Revenue Consultancy team recommends adopting a hybrid approach to monetization - using a mixed model of IAPs, system-initiated ads, and user-initiated ads.
