this is both a computer game and a board game.
the computer game is currently in version 4, and is probably the highest rated strategic computer board game out there. note: the category of "strategic computer board games" does not include purely abstract (computer) board games such as Chess, Checkers, and Blokus.
the board game attempts to recreate the feeling of the computer game, but unmodified hardly does so.
prior to Sid Meier there was an Avalon Hill Civilization board game. the latter has no connection to Sid Meier's version.
