As a kid The House of the Dead 2 & Centipede at the arcade & Smash Bros at "home" (or rather, Ekko's house, she never owned any consoles other than handhelds and her favorites on those are pokemon). She stops playing them in her early teens but if she hadn't: Rule of Rose and probably a FPS game which I don't like so idk, call of duty or something lol. She would have become one of those toxic online FPS players under different circumstances.
