In this chapter of The Hitchhiker’s Guide to Launching Live Service Games, we explore matchmaking and multiplayer aspects of live game development, their importance and impact on players, and technical areas that may require some extra attention. 

Understanding Matchmaking and Multiplayer

Matchmaking connects players with opponents or teammates of similar skill levels, creating balanced and fair matches. This ensures that players can compete on a level playing field, promoting healthy competition and avoiding frustration from encountering significantly stronger or weaker opponents. It helps to keep players challenged and motivated to improve their skills, thereby contributing to long-term retention and a thriving player base.

 

The multiplayer aspect of games allows players to collaborate, cooperate, or compete with one another in real time. This creates a dynamic and unpredictable gaming experience that can be immensely gratifying.

There are different types of multiplayer games that cater to various preferences and playstyles. Some multiplayer games fall into the cooperative category, where players team up to beat the campaign or tackle challenging missions together. On the other hand, there are match-based multiplayer games like Halo or Call of Duty, where players engage in intense competitive battles. For those seeking a more immersive experience, there are large-scale MMO (Massively Multiplayer Online) games like World of Warcraft, where players can interact in vast virtual worlds and undertake epic quests together.

Even in games that might not primarily focus on multiplayer, such as Elden Ring, there exists a semi-multiplayer aspect. In titles like Elden Ring, players have the opportunity to visit other players' worlds, creating a unique blend of single-player and multiplayer elements. This hybrid approach allows players to share experiences and occasionally collaborate, enhancing the overall gaming journey.

Regardless of the type of multiplayer gameplay, the multiplayer feature fosters camaraderie among players and encourages them to strategize, communicate, and work together. This collaboration not only enhances the gaming experience but also leads to deeper engagement with the game itself.
