I actually had to look up the "Trolley Problem" as I'd never heard of it. The game makes a whole lot more sense now! I'm not real sure how to take the core concept of the problem and make it fun though as it's rather grim either way! Off the top of my head (and this is from wayyyy out in left field), what if it were more of a game show/Total Carnage thing where you have a crowd either cheering or booing you on depending on your choice and the info that was revealed after your choice? You have to keep the crowd on your side or they revolt (you lose)?
