Games had been among the first in Britain to see evidence of the atrocities committed at the Bergen-Belsen concentration camp, when photographs taken there by British troops arrived at the War Office in 1945. The same year he produced a poster, "Give Clothing for Liberated Jewry", and would often work to support Jewish and Israeli organisations. Games, who was Jewish, spent some time in Israel in the 1950s where, among other activities, he designed stamps for the Israeli Post Office, including for the 1953 Conquest of the Desert exhibition and taught a course in postage-stamp design. He also designed covers for "The Jewish Chronicle" and prayer book prints for the Reform Synagogues of Great Britain. In 1960 Games designed the poster known as "Freedom from Hunger" for the Food and Agriculture Organization of the United Nations.
