This document discusses the benefits of building an app portfolio rather than focusing on individual apps. It notes that as people download fewer apps, advertising costs are rising, so cross-promoting within a portfolio of apps can help reduce acquisition costs. Building a portfolio also smooths out revenue across game lifecycles and protects against market sentiment shifts. The document recommends releasing multiple games and taking a strategic approach to cross-promotion, such as using optimized ad serving based on player data and creating a rich content ad portal to improve ad quality and engagement.
