Designing arcade games for universal accessibility presents several key challenges that developers must address to ensure inclusivity. One major challenge is creating intuitive controls that cater to players with varying physical abilities, such as those with limited mobility or visual impairments. Another hurdle is balancing difficulty levels to accommodate both casual and experienced gamers while remaining engaging for all. Additionally, incorporating customizable settings, like adjustable text sizes, color contrasts, and audio cues, is essential but can complicate development. Finally, ensuring fast-paced arcade mechanics remain accessible without sacrificing the core excitement of the genre requires innovative design solutions. Overcoming these challenges is crucial for fostering a more inclusive gaming community.
