Billed as "A party game for horrible people," anybody that's played can tell you this game lives up to its reputation. Cards Against Humanity has reached legendary status, starting as a simple Kickstarter project that received a modest $15,000+ in funding, the game has since generated well over 8 figures in revenue for the 8 co-creators, with very few expenses to eat into the profits. In fact, co-creator Max Temkin told Bloomberg in 2014, "None of us has to have a job for a very long time."
Even more famously, CAH has created such a devoted community around their product that they were able to sell 30,000 boxes of actual shit at $6 each. Yes, you read that right. They quite literally sold $180,000 worth of "bullshit." If that's not enough to get you to buy this game, I'm not sure what is.
