Dark December is a board wargame published by Operational Studies Group (OSG) in 1979 that simulates the Battle of the Bulge.

With straightforward rules and only 75 military units counters, the game has been characterized as "simple and playable"[2] — British critic Nicky Palmer gave it a complexity rating of only 25 on a scale of 100.

[3] The game uses a standard alternating "I Go, You Go" system, where the German player checks supply, moves, attacks, and constructs or demolishes bridges.

In Issue 78 of the British magazine Games & Puzzles, Palmer called Dark December "a curious amalgam of design techniques by Danny Parker."

Palmer criticized the game's "unattractive" map but also stated that the "generosity in supplementary material does add to the pleasure of play.

Palmer was critical of the hard-to-read counters, poorly printed and similar in colour to the map colours, but gave the game an excellent Excitement Grade of 85%, saying, "The designer's suggestion that players restrict themselves to a 7½ minute time limit per move does look feasible ... allowing the completion of a fair-sized scenario in a few hours — a rare virtue nowadays.

Goldberg concluded, "One benefit of the proliferation of Bulge games is that each succeeding product must be at least above average to attract a decent market share.
