In computer and video games, a traditional game is a computer program adaptation of a non-computer game (such as a board game or card game). Board games and card games have been around for many years such as Go which is thought to have been around in ancient China more than 2,500 years ago, and although it is not known exactly when the game was invented. Backgammon is also thought to be one of the oldest two-player board game in the world. They are often ported to computer programs because of the ease of access and little need for set up time. They can be play on the internet or LAN between players helping them to become popular to play online.
