The 2023 Roblox Report, produced by GameAnalytics, provides a comprehensive analysis of player behavior and performance benchmarks across the Roblox platform. The study is based on 2023 data from thousands of games that utilize the GameAnalytics SDK, representing over 50% of total player engagement on the platform. The dataset includes a significant sample of high-performing titles, featuring 300 games with over one million monthly active users and 60 titles exceeding ten million monthly sessions. The findings reveal a highly fluid player base, with 47% of users accessing the platform via both mobile and desktop devices. Engagement is characterized by high frequency rather than single long sessions; over 50% of players engage at least twice daily, and the top 5% of games successfully bring players back more than 3.5 times per day. While the average session length for half of the tracked games is under six minutes, elite titles in the 95th percentile sustain engagement for nearly 30 minutes per session. Monetization remains a significant challenge on the platform. Only 4.2% of players spend Robux within games, and more than half of those spenders contribute less than $1 annually. However, a small segment of high-value "power spenders" drives the majority of revenue, with the top 5% of games earning approximately $77 per playing player annually. Retention is identified as a universal struggle across the platform regardless of game quality; Day 1 retention typically ranges between 12% and 15%, dropping to near 1% by Day 90. The report concludes that success on Roblox requires optimizing for cross-platform play, implementing aggressive LiveOps to counter natural retention decay, and focusing on session frequency to drive monetization.
