The 2025 Game Developer Survey captures the technology preferences and strategic shifts of game studios worldwide, focusing on platform targets, engine adoption, 3D creation tools, backend services, analytics, user‑acquisition solutions, and generative‑AI usage. By segmenting respondents across six studio‑size categories—from solo developers to enterprises with over 100 employees—the survey reveals how development priorities evolve as companies scale and as pricing models change. Unity remains the most widely used engine, yet studios of all sizes report a notable decline in planned future use, driven by Unity’s revised pricing that introduced a 25 % increase for enterprise licenses and an $2,200 per‑seat fee for pro users. Open‑source alternatives such as Godot and Defold are gaining traction, while Unity’s ProBuilder and SideFX’s Houdini emerge as the fastest‑growing 3D modeling and level‑design tools, especially among studios under 100 employees focused on PC and web titles. Conversely, Adobe’s suite and Autodesk products experience the steepest drop‑offs, with declines ranging from 4 % to 10 % in anticipated usage. Backend infrastructure shows a shift away from Photon, whose hybrid‑plus offering has sparked a modest decline, toward Edgegap, which leverages bare‑metal and cloud resources to deliver cost‑effective matchmaking. Xsolla’s recent rollout of loyalty programs, regional tiering, and cloud‑gaming integration underscores a broader move toward web‑based delivery and progressive‑web‑app capabilities, particularly in the MENA region. Analytics remain dominated by Google, but Mixpanel records a 120 % surge in interest, buoyed by a new startup‑focused pricing tier that promises over $150 k in value for qualifying studios. User‑acquisition trends indicate a universal retreat from Apple Search Ads after its shift to a cost‑per‑tap model, while privacy‑centric platforms such as Tenjin and Branch experience rapid adoption, leveraging OpenAI‑enabled features and enhanced compliance tools. Generative AI is employed across a spectrum of development stages—from storyboarding to performance optimization—but studios report a consistent decline in its use for content creation, with smaller teams showing a 7 % drop and larger teams a 5 % reduction. Overall, the survey highlights a diversification of technology stacks, a cautious response to pricing reforms, and an accelerating embrace of open‑source, cloud‑native, and AI‑augmented solutions as the industry navigates
