I found Papers, Please to be a really fascinating game. I've been on a indie binge lately (Firewatch is another recent favorite) and I felt Papers, Please had a really great story that a lot of indie games are missing. Plenty of options and tough choices to make, with different outcomes for everything.

I also appreciated that I could walk away at any point and pick it up later. I didn't feel "trapped" having to finish a mission like too many AAA games. Well worth the ten bucks in my opinion.
