You can have a lot of fun with a plain old deck of cards. https://boardgamegeek.com/wiki/page/Standard_Deck_Playing_Card_Games

I'm trying to cull my collection to one shelf per game genre. Here are the ones that made the cut for my co-op shelf:

• The 7th Continent (2017)
• Agents of SMERSH (2012)
• Burgle Bros. (2015)*
• Dawn of the Zeds (Third Edition) (2016)
• Flash Point: Fire Rescue (2011)*
• Forbidden Desert (2013)
• Freedom: The Underground Railroad (2013)
• Ghost Stories (2008)*
• The Grizzled (2015)
• Horrified (2019)
• The LOOP (2020)
• Pandemic: Iberia (2016)*
• Police Precinct
• Wok Star (2010)
• Zombicide (2012)

The four with asterisks are my favorites.
