„Chrononauts is a fascinating, whimsical exploration of time travel, causality, and possibility covering many fascinating and significant events of the last century or so.“
– Andrew Looney
„Chrononauts“ by Anrew Looney (2000) is a card-based game where the players play time travellers able to alter historical events by flipping specific cards, linchpins of the timeline. Those altered events may cause a ripple effect by altering follow-up events, some quite obvious, some funny and nifty: Why would the New York World Fair 1939 have German Cake in an alternate timeline?
