In the world of gaming, backward compatibility refers to a gaming system that is capable of running games that were created for an earlier version of the system. This is an important attribute to consider when purchasing a new gaming console if you hope to play older games that are perhaps no longer produced. Backward compatibility can also open up the world of potentially available games, as certain game sellers continue to sell older games even when newer versions are released in conjunction with new editions of gaming consoles.
