In 'Chrono Chums: Whose Hello Is It Anyway?', players take on the role of Phyllis, a quirky time-traveling historian with a knack for accidentally altering timelines. As Phyllis hops through pivotal moments in history to rekindle her long-lost friendships, she inadvertently introduces absurdities that cause time to fold in hilarious ways. Between attending a wild Renaissance Festival where she must outwit a rival historian and participating in a Wild West shootout that turns into an impromptu musical, players must navigate humorous dialogue choices, bizarre quests, and chaotic character interactions to restore the timelines while keeping history hilariously intact. Will her friendships survive the test of time—or will they go down in history as the most dysfunctional duo ever?
