Papers, Please offers you choices and each choice has an impact that isn't always easy to forsee. In one game, I took a bribe that later got me arrested. In one game, I was moving so slowly I couldn't make rent and was thrown into prison. At one point, a man told me him and his wife were immigrating and that I "should treat her kindly." She didn't have the correct papers and when I let her through, I got a citation that led to a fine.
Papers, Please is a great game in that as I played it I considered what the "right thing to do" was and then what would be the best thing for my family. It's also a strange thing to force someone into a body scanner and analyze the results. On one hand, we have the privacy invasion of body scanners but on the other hand, terrorists are blowing things up at your checkpoint.
Papers, Please is a game I recommend if you are looking for a unique experience that strays away from typical video game tropes. I wasn't sure it was possible to create an exciting game about working at the border of a small communist country, but Papers, Please does it for the glory of Arstotzka!
