What does Elliott request from his dad that he believes would be beneficial?

Elliott believes that playing "Kingdom of Krull" would be beneficial, which suggests that he sees value in engaging in this activity for reasons that could relate to skill development, strategic thinking, or simply enjoyment that improves his mood or social connection. This indicates that he may view gaming as a way to unwind, develop certain cognitive skills, or bond with others in a world he enjoys. The other options could offer experiences that foster connection or provide entertainment but do not necessarily reflect the same depth of perceived benefit that Elliott associates with playing "Kingdom of Krull."
