Gameplay is the primary metric

The ultimate metric for adopting or adapting any element of realism is its positive impact on gameplay. Does it make operations more immersive? More effective? More team-oriented? More enjoyable? If realism does not demonstrably improve one or more of these core aspects of the UNITAF experience, then it is not aligned with Part 2: Philosophy of Realism FM/G168 and should be reconsidered or rejected, regardless of its real-world counterpart.
