A lot of early Atari 2600 games (or, sorry, “Atari Video Computer System”, as it was called back then) were adaptations of games that could be played on the tabletop.

The convenience of playing them on the television was, of course, that you didn’t have to worry about physical components getting scattered all over the place, setup time and the like — if you just wanted a quick game of something with someone, all you had to do was slap in the cartridge, pick up a controller and you were away.

One example of this early brand of tabletop adaptation comes in the form of Concentration; perhaps not the most interesting game to play today, but kind of fun for two players, a good showcase of the Keyboard Controllers and a game with a certain amount of educational value, too.
