This document discusses video game subscriptions as a business model for publishers and platforms. It outlines how music and video streaming services led to the rise of subscriptions. Video games present unique challenges because they involve multiple stakeholders - publishers, platforms, and games.

The document analyzes the different types of revenue sharing models - license fees, development fees, and revenue sharing - and how game design should consider the incentives of each model. It argues publishers need to maximize player engagement like time spent and sessions to earn more from revenue sharing agreements.
