Posting again to suggest Frostpunk and Gods Will Be Watching, if you're looking for moral dilemma games that aren't RPGs.
For Frostpunk, I think Fall of Winterhome and The Last Autumn are more thunkful than the starting scenario. Gods Will Be Watching is relatively short and has rather brutal scenarios. Better if you can get it on sale, as it can be the wrong kind of frustrating sometimes.
For short games you can argue with, Refind Self is catching on with Holos and is available in English. Haven't played it myself. Looks like a trip.
