The premise of Chrononauts and Early American Chrononauts the same, so this will be a dual review. In the game, you are a Time Traveler with a Secret Identity and a Secret Mission.  Your job is to collect priceless artifacts, repair enough paradoxes, or change time enough to arrive back safely at your alternate timeline. For this example, we will be, Betty and our mission will be "The Scientists' Wish List." We can see on our card, that we want the year 1945 to be black and 1968 and 1969 to be red. (We'll get to how to make that happen.) For the artifacts, we need to collect any Live Dinosaur, the Crown of Thorns, and a Cure for Cancer.
