In 'Chrono Chums: Who's There?', players assume the role of a quirky time-traveling historian named Felix Fiddlesticks. After accidentally tangling with an ancient artifact during a convention, Felix gets sucked into a chaotic timeline where he encounters various historical figures turned 'chrono chums.' Players must engage in witty banter, solve paradoxical problems, and navigate the complexities of time as they attempt to restore the timeline before it collapses. With each decision affecting not only the present but the very fabric of history itself, every encounter brings both hilarity and dire consequences. Will you help Cleopatra survive the Romans, or start a fashion trend with Einstein that'll rattle the very foundations of science?
