In 'Chronochums: Hello, Who's There?', players take on the role of a quirky, time-traveling historian named Lex, who accidentally activates a malfunctioning device that allows them to communicate with various historical figures through the ages. As they explore pivotal moments in history, Lex must piece together fragmented conversations and clues to prevent a time paradox that threatens to erase key events from the timeline. Players choose dialogue options and make decisions that affect not only historical outcomes but also Lex's companions, a motley crew of characters from different eras, each with their own agendas. The game blends humor and drama, as players navigate encounters with figures like a bewildered Cleopatra, a sarcastic Shakespeare, and a futuristic robot trying to understand human emotions.
