Task: Explanation
Input (English): 18XX is the generic term for a series of board games that, with a few exceptions, recreate the building of railroad corporations during the 19th century; individual games within the series use particular years in the 19th century as their title (usually the date of the start of railway development in the area of the world they cover), or "18" plus a two-letter geographical designator (such as "18EU" for a game set in the European Union). The games "2038", set in the future, and "Poseidon" and "Ur, 1830 BC", both set in ancient history, are also regarded as 18XX titles as their game mechanics and titling nomenclature are similar despite variance from the common railroad/stock-market theme. Question: Are Shatar and 18XX games? Answer: yes
