Celtae

Celt — Latin Celta, plural Celtae — were an early Indo-European people who from the second millennium BCE to the first century BCE spread over much of Europe. Their tribes and groups eventually ranged from the British Isles and Portugal to as far east as Transylvania, the Black Sea coasts, and Galatia in Anatolia, and they were in part absorbed into the Roman Empire as Britons, Gauls, Boii, Galatians, Celtiberians, and Lusitans. Celtae is a "worker swapping" game powered by a rondel
