This game left me bristling with indignation, and I can't tell whether it was the subject matter or the way it was handled.
The fiction is competently executed. The writing is clear, and the author evokes specific themes and moral challenges without descending into bloated, over-wrought exercises in highly detailed tedium.
Interactively, it's a friendly gauntlet structure. The player has some agency to affect the story outside of key decision points that will always be used to set up specific dilemmas. And that's a great structure! It is often used to effectively provide interactive opportunities while confining a game's scope to a manageable size.
My major grumble is the way that The Milgram Parable works to present pairs of flawed options (or in one case, no options at all) before scolding the player's choice. It kept reminding me that I was in an exercise contrived someone else, reinforcing that the easiest way to win was by not playing. The repeated references to the Milgram experiment, and its concerns about justifying terrible things by "just following orders," undercut the idea of questioning my morality.
I especially resented the way that the game kept telling me how to feel. “What are you doing here? What have you gotten yourself into?” The game does not need to ask me these questions. Reading “You wish you knew more about what was going on” was irritating; there’s a subtle-but-important difference between me wishing I knew what was going on and the author telling me that I wish I knew more. Lines like these kept reinforcing the idea that me, the guy at the computer screen, was not the same person as the character in the adventure.
(Spoiler - click to show)I was exceptionally annoyed when I was told “You have no choice. Truly no choice at all,” after shooting the kid. I was quite aware that the choice was taken from me by the author, which circles back to my earlier point about this game spending too much time telling me how I was supposed to feel.
