RE: Papers, Please - Simulator of Communism
I was also surprised how detailed and authentic it actually is. I always thought I checked everything and still got Protocol Violation announcement. Or when confiscating a passport, I automatically assumed that it should be denied. You're learning everything on the march. Every day I missed at least one detail. There is just too many information to check.
And even though you're doing the same thing again and again, the game will catch you, and won't release, because almost every day an interesting situation is going to happen and it's fun to discover and solve it.
So if you like its theme, you should definitely try it. As I say, I thought it'll be terribly boring, but I was surprised. Six hours are speaking for themselves, and I'm only at the first fifth.
