Multiplatform functionality has evolved from a competitive advantage to an expected feature in 2025. Major publishers now prioritize cross-platform play and unified progression systems, breaking down historical barriers between console, PC, and mobile ecosystems. This shift creates larger player pools, extends game longevity, and enables friends to play together regardless of hardware choice. Technical implementations have matured, with standardized APIs and improved matchmaking systems addressing input balance concerns. However, platform holders navigate complex business relationships, and some exclusivity deals still create fragmentation. Mobile-console cross-play particularly shows explosive growth. What games have implemented cross-platform features most successfully? Are there genres where it works better than others? Share your experiences with cross-progression systems and whether platform-agnostic gaming is truly becoming universal or if significant gaps remain.
