Papers Please is good. I don't think the game is a commentary on communism, but more on bureaucracy. The creator's other solo dev game Return Of The Obra Din is another game centered around bureaucracy. You (the player) are constantly hounded for money because of daily rent and heat expenses, and you only make money per person processed, but also must make moral choices throughout the game. For example, at some point a new border guard introduces himself to you and says he is from the same town as you. He offers a cut from the money is get processing detainees, which incentivizes you to detain anyone given the option. Eventually he tells you his lover will be attempting to cross the border, when she gets there, she does not have the proper paperwork and she pleads with you saying she will die if she can't be reunited with her love. Do you take the hit to your income and let her through? There are many such occurrences like this in the game, which makes it good
