A monster game is a game that is either very large, very complex, or both. One criterion sometimes adopted is the number of pieces; a game which puts greater than 1000 counters into play at once may be considered to be a monster game. This classification can technically be applied to any board game, but most commonly refers to the kind of non-abstract wargames in which a large amount of time is needed to play each turn as a result of a relatively high commitment to period accurate military realism. Drang Nach Osten and its companion, Unentschieden led to the Europa Series games, a giant WWII game.
