"Síochán leat" (Irish for "peace be with you") chronicles the history of her children's heritage. Romero made the game following "The New World", a game she originally made to teach her daughter about the slave trade. Romero designed "Síochán leat" to teach her daughter about her Irish heritage and traces the family's history from the Cromwellian invasion of Ireland to their ancestor's eventual immigration into the West Indies on the paternal side and Canada on the maternal side. The game features a burlap pillow simulating an earthen mound covered by 26 pieces of grass, each representing a county in Ireland. In a talk given at the Austin Game Developers Conference in September 2009, Romero noted that the burlap was filled with mementos of her upbringing and her heritage, including photographs of her great grandfather, Paddy Donovan, and one of her mother's rosaries. On her blog, Romero notes that, "the game is signed in many ways and is highly autobiographical. It is my history and it also reveals my feelings about its present state."
