Pandemic is a cooperative board game designed by Matt Leacock and published by Z-Man Games in 2007.
 "Pandemic" is based on the premise that four diseases have broken out in the world, each threatening to wipe out a region.
 The game accommodates 2 to 4 players, each playing one of five possible specialists: dispatcher, medic, scientist, researcher, or operations expert.
 The game is unlike most board games in that the gameplay is cooperative, rather than competitive.
 Through the combined effort of all the players, the goal is to discover all four cures before any of several game-losing conditions are reached.
In a cooperative board game, players work together in order to achieve a goal, either winning or losing as a group.
 As the name suggests, cooperative games stress cooperation over competition.
Vanished Planet is a cooperative board game that debuted at the World Boardgaming Championships in 2003.
 "Vanished Planet" pits the players against a time limit; the players must succeed in a certain number of goals before this time limit is reached, or they all lose.
Mechs vs. Minions is a cooperative board game made by Riot Games, released in October 2016.
 "Mechs vs. Minions" is set in the same world as "League of Legends".

The Boardgamer was a magazine founded by Bruce Monnin after Avalon Hill was bought out by Hasbro and the future of their board games was in doubt.
 The magazine was published between 1996 and 2004.
 The intention was to continue support for Avalon Hill products in the same way "The General" had, as well as (according to Monnin in issue 46 of "Operations Magazine"), any games contested at the World Boardgaming Championships.
Flash Point: Fire Rescue is a 2011 thematic cooperative board game designed by Kevin Lanzing with the help of firefighters.

 These include fires in a high rise building, a two-story house, and a submarine.
The World Boardgaming Championships is a convention held yearly since 1999 by the Boardgame Players Association.
 It was previously held in Lancaster, Pennsylvania, but it moved to the Seven Springs Mountain Resort in 2016.

 This convention replaced Avaloncon, which had been run from 1991 to 1998 by Avalon Hill.
Zombiepox (also ZOMBIEPOX) is a cooperative board game in which players fight the spread of zombies that threaten to take over the town.
 It was developed by Tiltfactor Laboratory, a game research center located at Dartmouth College, New Hampshire, focusing on games and play that investigate and explain ideas.
Hex is a strategy board game for two players played on a hexagonal grid, theoretically of any size and several possible shapes, but traditionally as an 11×11 rhombus.
 Players alternate placing markers or stones (Go stones make ideal playing pieces) on unoccupied spaces in an attempt to link their opposite sides of the board in an unbroken chain.
 One player must win; there are no draws.
 The game has deep strategy, sharp tactics and a profound mathematical underpinning related to the Brouwer fixed-point theorem.
 It was invented in the 1940s independently by two mathematicians, Piet Hein and John Nash.
 The game was first marketed as a board game in Denmark under the name Con-tac-tix, and Parker Brothers marketed a version of it in 1952 called Hex; they are no longer in production.
 Hex can also be played with paper and pencil on hexagonally ruled graph paper.
