>>108224528>VIDEO GAMES ARE STUPID LOLShe liked video games a lot at first; things go south when she takes failure way too seriously. This implies she's lived with strident expectations of success and she's unfamiliar with frivolous situations where you try to succeed but failure doesn't really matter. It's a good piece of characterization.
She calls video games a waste of time, but her demeanor and the rest of her lines indicate she meant it in a positive way; this is a person who hasn't been permitted to "waste" time perhaps since she was nine years old.
Mike's hang-up about video games is him overcompensating.
