Engagement Optimized Matchmaking (EOMM): Unveiling the Controversial Algorithm in Gaming

EOMM stands for Engagement Optimized Matchmaking. It’s a matchmaking framework increasingly used in online multiplayer games that prioritizes player engagement and retention over other factors, such as skill level or connection quality. The goal is to keep players playing for longer periods, even if it means creating matches that aren’t perfectly balanced in terms of skill.

Understanding the Mechanics of EOMM

How EOMM Works

Unlike traditional Skill-Based Matchmaking (SBMM), which aims to pit players against opponents of similar skill levels, EOMM focuses on maximizing player retention. This is achieved by analyzing player data, such as win-loss ratios, play time, spending habits, and even emotional responses to certain in-game events. EOMM then uses this data to create matches designed to elicit specific emotional responses and behaviors, ultimately leading to longer play sessions.

The Optimization Problem

The core concept behind EOMM is framing matchmaking as an optimization problem. Instead of simply trying to create fair matches, the algorithm seeks to find the combination of players that will result in the highest overall engagement. This can involve various strategies, such as pairing players with opponents who are slightly better or slightly worse, strategically inserting easier matches after a series of losses, or even creating teams with a mix of skill levels to encourage teamwork and communication. The algorithm is designed to learn from past player behavior and continuously adjust its matchmaking strategies to achieve optimal engagement.

Concerns and Controversies

EOMM has sparked considerable debate within the gaming community. Many players argue that it creates unfair and frustrating matches, prioritizing player retention over competitive integrity. Common criticisms include:

• Inconsistent Match Quality: Players report experiencing wide swings in match difficulty, with periods of easy wins followed by seemingly unwinnable games.
• “Rigged” Matches: Some players believe that EOMM deliberately manipulates matches to create specific outcomes, such as forcing a 50% win rate or incentivizing players to purchase in-game items.
• Punishing Skilled Players: High-skilled players often find themselves matched against equally skilled opponents consistently, leading to intense and stressful matches.
• Smurfing: The use of alternate accounts to avoid EOMM is a common practice that exploits the system.

Frequently Asked Questions (FAQs) About EOMM

Here are some frequently asked questions about EOMM to further clarify its complexities and implications:

1. What is the difference between EOMM and SBMM? SBMM prioritizes matching players based on their skill level to create fair and balanced matches. EOMM, on the other hand, prioritizes player engagement and retention, potentially sacrificing match fairness to keep players playing longer.
2. Which games are known to use EOMM? While companies are often secretive about their matchmaking algorithms, games like Call of Duty, FIFA, and potentially Overwatch 2 have been suspected of using EOMM or similar engagement-based systems. Many players also feel that Apex Legends manipulates the player retention with an algorithm that gives “intentional bad games”.
3. How can I tell if a game is using EOMM? It’s difficult to definitively prove that a game uses EOMM, but signs can include inconsistent match quality, drastic swings in difficulty, and a feeling that matches are predetermined.
4. Is EOMM always a bad thing? Not necessarily. Proponents of EOMM argue that it can create a more enjoyable experience for casual players by providing a mix of challenging and rewarding matches. However, its impact on competitive integrity remains a significant concern.
5. Does EOMM promote player retention? Yes, that is the ultimate goal. By creating matches that are designed to elicit specific emotional responses, EOMM aims to keep players engaged and playing for longer periods.
6. How does EOMM collect data about players? EOMM systems collect data from various sources, including in-game statistics (win/loss ratios, kills, deaths), playtime, spending habits, and even emotional responses inferred from player behavior.
7. What is Engagement-Based Matchmaking (EBMM)? EBMM is another term for EOMM. The terms are largely interchangeable, and both describe matchmaking systems that prioritize player engagement and retention.
8. Can a VPN help avoid EOMM? While a VPN can sometimes help bypass SBMM by connecting to servers in regions with potentially different skill levels, its effectiveness against EOMM is less certain. EOMM algorithms often rely on more sophisticated data analysis, making them harder to circumvent.
9. How do developers justify using EOMM? Developers often argue that EOMM is necessary to maintain a healthy player base and ensure that casual players don’t get discouraged by constantly facing highly skilled opponents. They also claim it can lead to more varied and enjoyable gameplay experiences.
10. What are the ethical considerations of EOMM? The ethical implications of EOMM include concerns about manipulation, fairness, and transparency. Players have a right to know how matchmaking works and whether their experience is being deliberately manipulated for profit.
11. What is the future of matchmaking in online games? The future of matchmaking will likely involve a combination of SBMM and EOMM principles, with developers seeking to strike a balance between creating fair matches and maximizing player engagement. Transparency and player feedback will be crucial in shaping this future.
12. Where can I learn more about the psychology of gaming and learning? The Games Learning Society is a valuable resource for understanding the intersection of games, learning, and player behavior. Visit their website at GamesLearningSociety.org. You can also find more information about game design principles and player psychology through academic research and industry publications.
13. Is it possible to “beat” EOMM? There are various strategies players use to attempt to “beat” EOMM, such as quitting after losses or using alternate accounts. However, the effectiveness of these strategies is debatable, as EOMM algorithms are constantly evolving.
14. How does EOMM affect the competitive scene in esports? EOMM primarily affects casual and ranked play. In esports, professional tournaments and leagues typically use custom matchmaking systems that prioritize fairness and competitive integrity.
15. Are there any alternatives to EOMM? Yes, developers can explore alternatives such as prioritizing connection quality, offering multiple matchmaking options (e.g., ranked, unranked, casual), and providing more transparency about how matchmaking works.

Conclusion: Navigating the EOMM Landscape

EOMM is a complex and controversial matchmaking framework that has a significant impact on the online gaming experience. While it aims to enhance player engagement and retention, it often comes at the cost of match fairness and competitive integrity. Understanding how EOMM works, its potential drawbacks, and alternative approaches is crucial for both players and developers to navigate the evolving landscape of online gaming. Continuing the dialogue and seeking more transparency will ensure that matchmaking systems prioritize both player enjoyment and fair competition.
