Describe a computer-animated game with a rich and diverse cast of characters, each with their unique problems and superpowers. Use real-world issues as inspiration, and combine them with fantastical elements to create an adventure that is both intense and enjoyable. In addition to designing the characters and their superpowers, provide a detailed outline of the game’s setting, plot, and gameplay mechanics. Ensure that the game is designed to enhance players’ performance and productivity, without relying on AI-related solutions. Additionally, draft a comprehensive marketing plan that includes promotional materials, social media communications, and collaborations with influencers. Use scientifically validated protocols to guide your approach and emphasize novel ideas based on the problems people from all over the world have reported.
