Backgammon
Backgammon is one of the oldest known board games. Its history can be traced back nearly 5,000 years to archeological discoveries in the Middle East, originally in Iran. It is a two player game where each player has fifteen pieces ("checkers") which move between twenty-four triangles ("points") according to the roll of two dice. The objective of the game is to be first to "bear off", i.e. move all fifteen checkers off the board. Backgammon is a member of the tables family, one of the oldest classes of board games.
Board wargame
The most recent of the major types of board wargame, it was created by the game "We the People" published by Avalon Hill in 1994. In most aspects it is much like a typical board wargame (on the simpler side of the spectrum), but play is driven by a deck of cards that both players draw from. These cards control "activation points", which allow the use of troops, as well as events that represent things outside the normal scope of the game. Newer card driven games have helped reinvigorate the war game genre as well as other differently themed games. "Twilight Struggle", a game based on the Cold War, was ranked #1 on the website BoardGameGeek from December 2010 to January 2016. As of September 2018, it's ranked fifth overall but first for wargames.
