Electronic gaming has become the largest entertainment category by consumer time spent globally, larger than film and music combined. The business model evolution — from one-time game purchases to live services with ongoing monetization through downloadable content, subscriptions and in-game purchases — has fundamentally changed the economic profile. Live service games with large engaged player bases generate recurring revenue that extends well beyond initial release, creating compounding value from established franchises. Mobile gaming has dramatically expanded the addressable player base, though monetization dynamics in mobile are different from console and PC. The key metric for live service success is daily active users and the revenue generated per user through engagement monetization. Franchise IP has become enormously valuable: established game universes with loyal player bases sustain engagement across multiple platform generations and content releases. For investors, gaming companies with leading live service franchises generating strong DAU and ARPU metrics offer relatively predictable recurring revenue, while pure game release businesses remain hit-driven with high earnings volatility tied to individual title performance.
