Playgama has launched an AI Game Index to rank coding agents based on player engagement metrics from 4,200 games. The index tracks performance data for titles published between September 22 and October 21, 2026.
Why it matters
The index provides a quantitative measure of whether AI-generated code results in content that keeps players engaged. This moves the evaluation of coding agents beyond basic syntax generation toward functional player retention outcomes.
Astra-built games achieve a median playtime of 4 minutes 58 seconds, while OpenCode-built titles lead at 5 minutes 14 seconds. Claude Opus maintains a 54% share of new games published on the platform.
The players
Playgama
A gaming platform founded in 2023 that facilitates AI-assisted game development for over 4,000 active developers.
The details
The index calculates performance after a game reaches at least 20 plays and a model completes 15 games. A play is defined as a session lasting at least 30 seconds, with ranking metrics derived from developer-submitted model data. OpenCode, which currently accounts for 1.6% of platform games, performs strongly on session duration despite its lower relative volume.
Timeline
September 22 - October 21, 2026: Data collection period for the initial index.
October 2, 2026: Date Astra market share dropped below 5% daily.
October 29, 2026: Official launch of the Playgama AI Game Index.
The Tech Race
The index follows a broader industry move toward establishing performance benchmarks for generative coding agents. It contrasts with standard static code evaluation by focusing exclusively on player engagement metrics.
Developers using the platform can now compare how different model choices affect player retention metrics. The index updates daily, providing a real-time feedback loop for creators choosing between Claude, Astra, Codex, or OpenCode agents.
The takeaway
The index provides a standardized way to measure if AI-assisted code actually keeps users engaged. Creators should monitor the daily updates to see if OpenCode maintains its session duration lead against larger models like Claude Opus.
