The game format doesn't really do much here. Of course extremely long lines, abusive bosses, distant polling locations and abusive election observers are bad. Clicking yes/no doesn't really get the point across better. I'd rather read an article with some research about how different demographics are impacted. Heck, ending the game with a link to some statistics would have been good (correct me if I missed them).

I want to juxtapose this with another game with a social message: Cart Life. It had you making decisions as a low income worker. As the game went on your series of problems and decisions start accumulating in a way that helped communicate that small problems in the right place for people with no safety net can be disastrous.

I guess what I'm trying to say is that a game is a good way to communicate interactions between things or events in an easy to digest way, but probably a bad way of communicating a simple "this exists" message, since a game can contain whatever you imagine.
