Unite Seoul 2025 -- The Real Start Is After the Game Ends: The developer conference Unite Seoul 2025 hosted by Unity held in Seoul on April 15, 2025 focused not only on technical advances in the game industry but on business strategies after that. The GROW track that provided the most practical insights was a session specialized in monetization and user acquisition strategy, focused on strategy after commercialization. GROW track insights: the game business challenge is not just making a good game but making a game that can sustain a business; user acquisition cost (UAC) has increased dramatically as mobile advertising efficiency declined; the post-launch lifecycle management -- when to update, how to retain players, how to monetize without alienating the community -- determines whether a game succeeds long-term; Unity analytics tools presented at GROW track enable data-driven decision making for all these post-launch challenges. The Korea game industry context: Korean mobile games have historically been strong at initial launch metrics but weaker at long-term retention; the GROW track lessons about lifecycle management and community engagement are particularly relevant for Korean studios trying to extend game lifespan in competitive global markets.
