GrowthBook
An experimentation platform combining remote flags, A/B tests, metric definitions, statistical analysis, and many data warehouses.
Why use it
Online games can expose tutorial, economy, or interface changes to a small cohort, then ramp or roll back against defined metrics.
Where it fits
Use analytics, feedback, player support, and updates to fix issues and decide what to improve after launch.
What to check
Experiments need adequate samples and sound statistics, while bad metrics reward short-term behavior; client flags cannot protect secrets or authoritative logic.
