Duround Sanctum Studio Game Development Services Plan
Stage-by-Stage Bug Fixing in Unity Game Engine
During Development

Fixing a bug may cost $100–$500 since developers are already working in the codebase
Staging/QA

Costs can increase up to 6× higher (around $600–$3,000 per bug) due to rework, re-testing, and code rewrites
Production (released)

Fixing a bug can cost 4–5× more than staging, sometimes 30× more than catching it early (e.g., $3,000–$15,000 per bug)
