Want to know the inner thoughts of others? Try playing a game like Apples to Apples. It’s an innocent way to see how others think with their responses and answers, and it is a fun game.
If you want to bump this up a notch then go for Cards Against Humanity. Same concept but more mature themed. Just a warning, you may need to reference the Urban Dictionary to understand some of the off-color terms.
Technically, Cards Against Humanity is an open sourced game and you can make your own set, but at $25 for a nicely printed, boxed set, it’s probably worth the cost.
