Gemini 3 Pro Image is worth comparing with a suitable Flash image model for complex, policy-permitted game art: several subjects, reference sheets and precise composition instructions. Google positions it for professional asset production, with reference-guided editing and higher-resolution output options. Choose between them by the usable assets and correction time your brief produces, rather than resolution alone. Check the exact endpoint and reference limits before building around the Nano Banana Pro name. Google’s hosted content rules, search grounding and watermarks all affect the workflow. Keep important game UI text editable, even if generated signage looks convincing.
