Brutally Honest #138: User Acquisition in the Post IDFA World

This analysis explores evolving user acquisition (UA) strategies and creative trends within the mobile gaming industry during late 2024. The primary thesis suggests that successful UA in a post-IDFA environment requires a shift from simple cost-per-install (CPI) metrics toward a holistic evaluation of creative performance, integrating return on ad spend (ROAS), budget scalability, and deep engagement metrics.

Key findings highlight the "river fence" mechanic as a dominant creative trend. Originally popularized by Idle Lumber in 2022, this visual hook—which involves a barrier stopping the flow of objects—has successfully transitioned from idle games to 4X strategy titles like Whiteout Survival and Sea of Conquest. The data indicates that cross-genre adaptation of successful idle mechanics is a viable strategy for scaling UA in more complex genres. Furthermore, the launch of Age of Empires Mobile serves as a case study for the limitations of brand nostalgia; despite generating approximately $11 million per month, the analysis concludes that nostalgia alone is insufficient for top-tier scaling without the integration of modern mobile mechanics like mini-games and "gates" features.

The scope of the commentary covers global mobile gaming markets with specific mentions of developers in Armenia, China, and the United States. Methodology relies on qualitative creative auditing and quantitative performance tracking of top-grossing mobile titles. The findings emphasize that for new games, developers should produce one to two new creatives weekly and prioritize Installs Per Mille (IPM) alongside retention data to ensure that creative hooks align with long-term player value. Professional opportunities in the sector remain robust, with significant hiring activity noted across monetization, ASO, and performance marketing roles at major firms such as Supercell, Playtika, and Moon Active.
