This document discusses strategies for soft launching a mobile game or app. It recommends conducting a soft launch for 2-3 months to collect user data from a test market in order to make data-driven decisions before a full launch. Key metrics to measure include user acquisition costs, retention rates, user experience, monetization, and game economics. The soft launch should integrate both install attribution and in-app analytics to track user behavior. Additional tips provided include choosing test markets carefully, focusing on product over branding, and planning soft launches for 2-3 or ideally 6 months.
