Designing arcade machines for military or training use presents unique challenges that go beyond typical entertainment systems. One major hurdle is ensuring durability, as these machines must withstand harsh environments, frequent use, and potential rough handling. Another challenge is achieving high levels of realism to effectively simulate combat or tactical scenarios, requiring advanced graphics and responsive controls. Integration with existing military training systems and software also complicates design, as compatibility and security are critical. Additionally, balancing cost-effectiveness with cutting-edge technology is a constant struggle, as budgets often limit innovation. Finally, maintaining user engagement while meeting strict training objectives demands careful attention to gameplay mechanics and feedback systems. Addressing these challenges is essential for creating effective and reliable training tools.
